How synthetic organic chemistry can help to feed the world

Chemistry for Tomorrow’s World 2012: Using Chemistry to Improve Agricultural Productivity – a policy event

Azoxystrobin is the world’s leading agricultural fungicide. It is a fully synthetic compound, whose invention was inspired by the structure and activity of the naturally-occurring fungicide strobilurin A. Today it is used worldwide to control fungi growing on over 120 types of crop, improving plant health, raising quality and increasing yield. The success of the project highlights the crucial importance of chemistry in meeting grand challenges such as global food security and the broader applicability of skills such as natural product synthesis. Keynote speaker Dr John Clough led the team of chemists at Syngenta that invented azoxystrobin. He will discuss the key role that synthetic organic chemistry played in creating an effective and safe fungicide. This policy event is organised by the Royal Society of Chemistry as part of a series of lectures designed to bring together active researchers and policy makers to highlight the role of the chemical sciences in tackling societal issues.

Be inspired - The Chemistry Centre

This event will be held in the Chemistry Centre on 26 September at the RSC’s recently refurbished building in Burlington House, London. Doors will open at 17:30 for refreshments. The event will begin at 18:00 and will finish with a wine reception. Please follow the link here for information and to register for the event.

What’s new with carbon dioxide?

In this tutorial review, Donald Darensbourg and Stephanie Wilson highlight the recent advances in the copolymerisation of carbon dioxide (CO2) with epoxides (oxiranes) to produce polycarbonates.

The advances in this area are discussed with specific reference to catalysts that have been designed to afford high selectivity for the copolymer versus cyclic carbonate formation.  The authors not only illustrate the advances in poly(propylene carbonate) (PPC) production by also investigate the underlying reasons for the differences in the reactivity of propylene oxide and cyclohexene oxide. 

Darensbourg and Wilson conclude by highlighting the need for improved catalysts which can prevent the degradation of PPC in the presence of azide ions – specifically those catalysts with appended amines or ammonium salts.

One-pot reduction of 5-hydroxymethylfurfural via hydrogen transfer from supercritical methanol

Scientists from Denmark and the USA have achieved efficient conversion of 5-hydroxymethylfurfural (HMF) to valuable chemicals over a Cu-doped porous metal oxide catalyst in supercritical methanol.

HMF (readily obtained from hexose sugars) has been identified as a key platform compound to generate useful renewable chemicals for the fuel industry, such as 2,5-dimethylfuran (DMF) and 2,5-dimethyltetrahydrofuran (DMTHF).  However, achieving selective transformation of HMF to a specific product and preventing the formation of undesired side-products remains a challenge.

In this work, a collaboration between scientists at the Technical University of Denmark, Yale University (USA) and the University of California Santa-Barbara (USA) led by Katalin Barta and Andreas Riisager have developed an one-pot procedure for the reduction of HMF.  The catalyst was prepared in aqueous solution from inexpensive and earth-abundant starting materials before undergoing calcination.  By tuning the reaction temperature, DMF or DMTHF and 2-hexanol could be obtained as the major products, and no formation of higher boiling side products or undesired char was detected.

Meet our Editorial Board: Walter Leitner (Chair)

Walter Leitner is a full Professor at Technische Chemie und Petrolchemie, Institut für Technische Chemie und Makromolekulare Chemie at the RWTH Aachen University and is the new Chair of the Green Chemistry Editorial Board.  As Walter takes up his new position, we asked for his thoughts on how sees the Journal, and the area of green chemistry, developing in the future…

Who or what initially inspired you to become a chemist?

I cannot fix this to a single person or event. To be honest, a large number of coincidences and external factors led me to study chemistry at Regensburg University, and it was mostly during my time as PhD-student with Henri Brunner and PostDoc with John Brown that I developed a strong research interest into catalysis and organometallic chemistry – and started to become fascinated by the idea of academic freedom!

You’ve recently been appointed as the new Chair of the Green Chemistry Editorial Board – what most excites you about the Journal?

The ever increasing scientific quality of the contributions and the incredible enthusiasm of the community – just coming back from the Green Chemistry Gordon Conference near Lucca in Italy, I am still nurtured by the same experience there!

Where would you like to see the Journal develop during your time as Chair?

Issue 9 of Green Chemistry now online!

The latest issue of Green Chemistry is now available to read online.

The front cover of issue 9 features work by Tomislav Frišĉić from the University of Cambridge (UK) and McGill University (Canada) and colleagues from Croatia, the UK and USA.  The authors discuss the concept of a solvent-free research laboratory which would eliminate the use of solvents for both chemical synthesis and the structural characterization.  The team used the mechanochemical click coupling of isothiocyanates and amines as the model reaction using an electrical, digitally controllable laboratory mill.  49 different thiourea derivatives were synthesized and all products were characterised by X-ray diffraction and solid-state NMR spectroscopy.

A model for a solvent-free synthetic organic research laboratory: click-mechanosynthesis and structural characterization of thioureas without bulk solvents, Vjekoslav Štrukil, Marina D. Igrc, László Fábián, Mirjana Eckert-Maksić, Scott L. Childs, David G. Reid, Melinda J. Duer, Ivan Halasz, Cristina Mottillo and Tomislav Friščić, Green Chem., 2012, 14, 2462-2473

The inside front cover of this issue highlights work by Chan Beum Park and co-workers from KAIST and Seoul National University, Korea, who report the synthesis of graphene-wrapped CuO hybrid materials by CO2mineralization.  These materials were created from CoCO3 microspheres mineralized on graphene oxide nanosheets and were shown to be promising materials for lithium ion batteries.  The hybrid materials demonstrated greatly enhanced stability and recyclability of the CuO anode for the Li ion batteries.

Synthesis of graphene-wrapped CuO hybrid materials by CO2 mineralization, Jong Wan Ko, Sung-Wook Kim, Jihyun Hong, Jungki Ryu  Kisuk Kang and Chan Beum Park, Green Chem., 2012, 14, 2391-2394

An interview with Martyn Poliakoff

Martyn Poliakoff is a Professor of Chemistry at the University of Nottingham, and the out-going Chair of the Green Chemistry Editorial Board.  As he steps down after leading the Journal for the last six years, Martyn took a few moments to talk to us about how he was inspired to become a chemist and how he sees the field of green chemistry developing in the future…

Who or what initially inspired you to become a chemist?

My father and grandfather were physicists.  From as young as I can remember, it was always assumed that I would become a scientist.  I was lucky to have inspirational physics and chemistry teachers, David Hepburn-Scott and Tony Roberts.  I was not good enough at maths to become a physicist but Tony Roberts really inspired me to focus on chemistry and I am still in contact with him nearly 50 years later.  (Find out more here)

What have you enjoyed most during your time as Chair of the Editorial Board of Green Chemistry?

I have really enjoyed meeting a variety of green chemists and also it has been a pleasure to promote the Journal across the world. 

What do you consider to be the most significant development on the Journal during your time as Chair?

I think there have been three important developments during my tenure.  Firstly, the greatly increased Impact Factor; the friendly rivalry with ChemComm has been a great spur to us all. Secondly, the increased rejection rate (including at least one paper of mine!) indicates not only that the Journal has become a more attractive place to publish but also that the standard of Green Chemistry publications is increasing.  Thirdly, the appearance of at least three new journals in this area clearly demonstrates that the foresight of the RSC in recognising the potential of green chemistry.  I am determined that our Journal shall remain the market leader.

What do you see as the biggest challenge facing the field of green chemistry?
