To celebrate the 15th anniversary of Chemical Science, we invited authors who published with the journal in its early years and contributed seminal papers since then to revisit their original work and reflect on how their field has evolved. In their new Reflection article, Alicia Casitas and Xavi Ribas return to their influential 2013 review on high‑valent copper species to examine a decade of discovery, debate, and conceptual refinement in organometallic copper(III) chemistry.

In 2013 the notion of isolable organocopper(III) complexes was still taking shape. The field was energized by the finding of copper‑catalysed C–H and C–X bond‑forming reactions, yet there remained fundamental questions:

How do these reactive species behave? What governs their selectivity? And what does “Cu(III)” truly mean in systems where ligand effects blur formal oxidation states?

Casitas and Ribas chart how these questions have guided the evolution of the field, highlighting both mechanistic breakthroughs and the nuanced electronic structures that continue to challenge understanding to this day.

Dissecting a Promiscuous Catalyst

Across different ligand environments and substrates, organocopper(III) complexes exhibit dramatically varied mechanistic profiles. These species sometimes follow pathways reminiscent of classical organometallic reductive elimination, other times behaving showcasing radical or redox activity. This mechanistic “promiscuity” has pushed chemists to refine both computational tools and spectroscopic strategies to capture transient structures.

Recent research published in Chemical Science illustrates these complexities. Fan and co‑workers exploited the distinct hydrogen‑atom‑transfer (HAT) and radical‑capture reactivity of two different copper(III) complexes, Cu(III)-OH and Cu(III)-F, to develop a decoupled approach to C(sp³)-H fluorination (https://doi.org/10.1039/D5SC06381G). This strategy sidesteps the longstanding challenge of expecting a single high‑valent metal complex to excel at both HAT and radical capture.

Illuminating Radical Pathways

The Reflection also highlights the continuing debate over the nature of formal Cu(III), particularly in CF₃‑bearing complexes. Photochemical activation strategies have provided a powerful platform for interrogating these species. In an elegant demonstration, Motornov, Beier and co‑workers used violet‑light irradiation to sequentially release all four CF₃ groups from a tetrakis(trifluoromethyl)cuprate(III) complex, enabling efficient C-H trifluoromethylation of (hetero)arenes and even biomolecules (https://doi.org/10.1039/D5SC07405C). Their mechanistic studies reinforce how photochemistry can reveal hidden facets of high‑valent copper intermediates while affording practical transformations.

The interplay of radical and organometallic pathways also features in the combined computational and experimental work of Mandal, Stahl and colleagues (https://doi.org/10.1039/D3SC03597B). Their study dissects N-fluorobenzenesulfonimide (NFSI)-based radical-relay reactions, mapping selectivity trends and evaluating competing pathways such as radical–polar crossover and reductive elimination from formal Cu(III) species.

Expanding the Copper Redox Landscape

New insights into copper(I)/copper(III) redox cycles continue to appear in unexpected places. Sneddon, Kerr and collaborators conducted a deep mechanistic study of a copper(I)-catalysed sulfonylative Suzuki–Miyaura reaction (https://doi.org/10.1039/D3SC01337E), revealing not only the expected Cu(I)/Cu(III) pathways but also a competing Cu(II)-mediated route. Their work highlights the interconnectedness of copper’s redox chemistry, which is explored in the Reflection article from Casitas and Ribas.

Following their early contribution to Chemical Science, this Reflection captures not just how far copper(III) chemistry has come, but how vibrant, and mechanistically rich, future research may be.

To celebrate the 15th anniversary of Chemical Science, we invited authors who published with the journal in its early years and contributed seminal papers since then to revisit their original work and reflect on how their field has evolved. In their Reflection article, Koji Nakano and Kyoko Nozaki look back on their 2010 study of bimetallic cobalt(salen) complexes, which revealed a cooperative bimetallic mechanism for the alternating copolymerisation of epoxides with carbon dioxide.

Read the Reflection, for free, here: https://doi.org/10.1039/D5SC90244D

Their original work showed that placing two cobalt centres in close proximity allows one to activate the epoxide while the other delivers the propagating carbonate species, affording an elegant intramolecular division of labour that enhanced catalytic activity. In their Reflection, Nakano and Nozaki outline how this discovery helped motivate subsequent developments in both homobimetallic and heterobimetallic catalysts for epoxide/CO₂ copolymerisation.

Bimetallic Catalysts Beyond Polymerisation

The mechanistic principles highlighted in the Reflection, that proximity, complementarity and cooperative activation are all essential, now underpin advances across a wide range of bimetallic catalytic systems.

Yue, Yang, Tang et al. recently achieved atomic‑level spatial precision of cobalt and nickel sites within a covalent organic framework, creating a highly active bimetallic catalyst for CO₂ photoreduction in which the two metals influence each other electronically (https://doi.org/10.1039/D5SC08435K).

Römelt, Apfel et al. show that a Cu^ICo^II cryptate complex exhibits strong synergistic behaviour in visible‑light CO₂ reduction, outperforming its mononuclear analogues (https://doi.org/10.1039/D3SC02679E). These examples underscore how strategically combining metals can unlock reactivity that neither metal achieves alone.

Broader Advances in Polymerisation Chemistry

Other recent studies in Chemical Science reflect that the same emphasis on mechanistic clarity and controlled monomer insertion noted in the Reflection article is essential beyond bimetallic systems.

Seidel and Sumerlin et al. present a practical strategy for accessing alternating styrene–propylene and styrene–ethylene copolymers by coupling RAFT polymerisation with mild photocatalytic decarboxylation, sidestepping long‑standing reactivity‑ratio limitations (https://doi.org/10.1039/D3SC03827K).

Meanwhile, Plajer et al. offer monomer‑centred guidelines for selectivity in sulfurated ring‑opening copolymerisation, showing how an understanding of backbiting, chain‑end stability and ring strain can deliver perfectly alternating poly(esters‑alt‑thioesters) (https://doi.org/10.1039/D4SC05858E).

Though distinct from bimetallic approaches, both studies reinforce that precise control of fundamental steps in chain growth, as showcased in the Reflection and original Chemical Science paper, enables new polymer structures and reactivities.

Looking Ahead

Nakano and Nozaki’s Reflection highlights how the principles of cooperative catalysis have shaped fifteen years of progress in epoxide/CO₂ copolymerisation. Recent advances in both bimetallic activation strategies and mechanistically informed polymerisation methods show that these ideas continue to influence catalyst and polymer design across the field.

Dr John Mack: It is extremely important to master how to use software such as Excel and Powerpoint to present their data sets as clearly as possible to the reviewer.

What makes a paper truly stand out for you when reviewing a paper?

Professor AnnMarie O’Donoghue: It can be difficult to give the necessary time to providing detailed, constructive, balanced reviews as we are all time-pressed, however, it is one of the most important contributions we can make to the community. Particularly for Early Career Researchers, I think it is very important to maintain a positive, constructive tone and highlight positive aspects of a manuscript in addition to potential areas for improvement.

Do you have any advice to our readers seeking publication in Chemical Science on what makes a good paper?

Professor Nathalie Steunou: I don’t have any advice to give, just an opinion. To write a good article is to concisely tell a creative scientific story and, as a result, send a message that is likely to be of interest to the entire chemistry community.

Are there any steps that reviewers can undertake to improve the quality of their review?

Dr John Mack: I think it is important to avoid only being harshly negative when it becomes necessary to outright reject a paper. Time should be taken to leave the corresponding author with a clear picture of what you think they will need to do in future to reach the level that they aspire to.

Professor AnnMarie O’Donoghue: It can be difficult to give the necessary time to providing detailed, constructive, balanced reviews as we are all time-pressed, however, it is one of the most important contributions we can make to the community.

This month, we’ll be highlighting Professor Anna Pasternak, Dr Joshua Barham and Professor Abhishek Dey. We asked our reviewers a few questions about what they enjoy about reviewing, and their thoughts on how to provide a useful review.

Professor Anna Pasternak, Institute of Bioorganic Chemistry, Polish Academy of Sciences. The research of Professor Anna Pasternak’s group is focused on development of novel, nucleic acid based therapeutics, such as ASOs, SSOs, aptamers, triplexes and G-quadruplexes, targeted towards cardiovascular and cancer diseases. The particular interest includes not only their biological activity but also structural aspects which are crucial to understand their action within living cells.

Dr Joshua Barham, University of Regensburg. Dr Joshua Barham’s research uses emerging technologies for chemical synthesis that are powered by safe, sustainable energy sources like visible light and electricity. His research group develops catalysts that harness these energy sources to access highly reactive chemical intermediates under very mild conditions. Their vision is to valorize this technology to streamline the synthesis of active pharmaceutical ingredients, utilize biomass feedstocks, and recycle persistent pollutants.

Professor Abhishek Dey, Indian Association for the Cultivation of Science. Professor Abhishek Dey is interested in understanding and facilitating chemical reactions involving multiple electron multiple electron reductions of small molecules.

What encouraged you to review for Chemical Science?

Dr Joshua Barham: Chem. Sci. is the RSC’s flagship journal and it is diamond open access. It is rare for a Chemistry journal with international visibility and impact as high as Chem. Sci. to be open access, and I strongly support this principle. Therefore, I want to contribute to maintaining the high standards of Chem. Sci. by providing an appropriately high level of scrutiny and thoroughness during the peer-review process.

Professor Abhishek Dey: It’s one of the top journals in chemistry where I enjoy publishing. I feel responsible to ensure that the scientific quality of the article and inclusive nature of this journal is maintained. Hence I review for Chemical Science.

What do you enjoy most about reviewing?

Dr Joshua Barham: I particularly enjoy when authors take critical reviewer comments seriously and approach the response in a collaborative rather than combative way. For example, I have reviewed papers where the proposed mechanism was initially surprising or key control reactions were missing, and once authors addressed this it changed the story of the manuscript in a major way. Such experiences show the crucial importance of peer review. It was highly satisfying for me as a reviewer to see the value and impact that my comments had on the final manuscripts.

Professor Anna Pasternak: The possibility to verify quality of the research and improvement of the articles, if necessary, is the most satisfying for me.

Professor Abhishek Dey: Being able to contribute to the scientific thinking of peers across the world.

What advice would you give a first-time author looking to maximise their chances of successful peer review?

Professor Anna Pasternak: Do not rush, make a story – write in such way that the reader will be interested in the article, use logical interpretation of the results, never over-interpret the data, support discussion with already published facts, and last but not least – ask a friend to read the draft critically and give you advice before submission – another point of view is invaluable.

As a diamond open access journal, Chemical Science makes this form of publishing an easy option. We cover all publication costs, so our community can read and publish with us for free.

We are real advocates for open access, and in this blog post, we will explain how it can improve research culture and benefit every single one of us. Interested in learning more? Explore our research or submit your article today.

Discover what you could achieve with open access

Greater impact for you

As a researcher, you will find that the biggest benefit of publishing open access is increasing the discoverability of your work. The number of potential readers of your publications increases significantly with open access. If anyone can access your research – including other scientists, funders, policymakers and the general public – then it is more likely to be cited and make an impact.

Every article we publish is diamond open access, but we don’t only rely on our publications being available to all to make an impact. We celebrate our community, offering promotional opportunities like #ChemSciVoices where our authors can discuss their research in a video or blog post. When you publish with us, you can trust that your research will find the communities it needs to.

Better research culture for all

The benefits of open access for individual researchers are clear – but how can it improve research culture too? Open access helps make sure that publications are visible, reliable and reproducible. Ensuring research findings are available to everyone, in any part of the world is the key to building a fairer, more equitable society – one where everyone can access and benefit from discoveries. Open access can also encourage greater multi-disciplinary collaboration, as scientists in all disciplines and subjects can access and inspire each other, so driving scientific progress faster. Chemical Science harnesses these benefits of open access for everyone, by publishing leading-edge articles that have undergone rigorous peer review, at no cost to the author.

What makes Chemical Science different?

Our diamond open access policy sets us apart from other journals. This policy means that our community can read our articles and publish with us for free. We cover all of the publication costs, so everyone can choose an open access path for their research. And this is only a possibility because we are a society publisher with a mission to disseminate scientific knowledge.

Fair and rigorous peer review

We see open access as part of a larger vision to improve research culture. It’s not enough to increase the accessibility of articles – we need to make sure that our publications are reliable and reproducible too. Providing a robust peer review process is one way we make sure our publications are reliable. In every submission, our peer reviewers are looking for novel ideas, progressive thinking and research that can make a real-world difference. This approach means that Chemical Science is a home to both accessible and impactful work.

The choice of transparent peer review

We are continually looking for ways in which we can increase the quality of our peer-review. For this reason, we now offer our authors the choice of transparent peer review, which aims to cultivate a more open and robust peer-review process. If an author chooses this option, the peer reviewers’ reports, authors’ responses and editors’ decision letters are published alongside the accepted article. Transparent peer review can:

• encourage fair and rigorous peer review
• amplify the hard work of our editors and reviewers
• allow scientists to learn from the published reports
• promote more constructive reviewer comments

Transparent peer review is compatible with both single- and double-anonymised peer review. And if you are a reviewer, you will stay anonymous during the process by default. As an author, you can opt in for transparent peer review at any stage before publication.

FAIR publications

Reproducibility is a key part of the open access picture for Chemical Science. We encourage our authors to make sure that the data in publications is FAIR (Findable, Accessible, Interoperable and Reusable), and we also ask authors to provide a data availability statement in their article. This can improve research culture by:

• supporting the validity of data and maintaining research reproducibility
• increasing transparency and encouraging trust in the scientific process
• enabling and encouraging the reuse of new findings
• giving authors credit through the formal citation of data

Author Contributions

We also ask all authors to provide an Author Contribution Statement as part of their article as standard. Author contribution statements are important as they can:

• provide transparency about who contributed to the research and in what capacity. It allows readers to understand the specific roles of each author in the study, which can be helpful for assessing the validity and reliability of the research findings. 
• promote inclusion and diversity by acknowledging the different types of contributions made by each author. 
• ensure that all authors are given credit for their work, and that those who did not contribute significantly are not listed as authors.
