Dalton Transactions in Chemistry World

A Dalton Transactions article on carbon monoxide releasing molecules based on rhenium has been highlighted by Chemistry World:

Vitamin scaffold turns silent killer into a healing hero

A way to deliver carbon monoxide into the body safely for therapeutic use has been devised by scientists from Switzerland.

Fabio Zobi and colleagues from the University of Zurich attached a vitamin B12 scaffold to carbon monoxide-releasing rhenium complexes to increase their biocompatibility. Read the rest of the news story on the Chemistry World website…

Hot Article: Triazamacrocycles templated on iron

Peter G. Edwards and colleagues from Cardiff University and the University of Southampton investigate P3 and As3 macrocycles on an iron template in this Dalton Transactions Hot article.

The authors look at 9-membered triphospha- and triarsamacrocycles with unsaturated benzo-backbones that they make using a [CpRFe]+ template.

The complexes from an interesting ‘cup-shaped’ cavity, which could potentially accommodate anions.

Hot Article: Cleaning up crude oil

A new system, using a solid state catalyst, to remove impurities from petroleum has been developed by US scientists.

With current oil consumption levels high, light crude oil reserves will be exhausted, giving way to heavy and extra heavy bitumen refinery feeds. These contain a higher proportion of large polycyclic hydrocarbons, together with N- and S-heteroaromatics, which need to be removed or transformed, without catalyst poisoning. Current methods to do this require high temperatures and pressures.

The catalyst made by the researchers, composed of ruthenium nanoparticles immobilised on a polymer, hydrogenates aromatic compounds under moderate conditions with no poisoning.

Hot Article: Understanding the intermediates in reductive coupling of carbon monoxide

Read this Dalton Transactions Hot article to find out about how uranium can reductively couple carbon monoxide, an interesting reaction in Fischer-Tropsch chemistry.

Jennifer Green and co-workers at Oxford University use density functional theory to look at the reductive di- tri- and tetramerization of CO. They look at the linear yne diolate complex which forms if there is no further CO to react with the dimeric C2O2 reaction intermediate, amongst other intermediates. With the insight provided by this computational study a better understanding can be gained of Fischer-Tropsch chemistry.

DD13: Inorganic Photophysics and Photochemistry

Dalton Discussions 13 will be held at the University of Sheffield in September next year. The meeting focuses on Inorganic Photophysics and Photochemistry – Fundamentals and Applications.

The aim of the meeting is to bring together people from a wide range of disciplines – from theory and ultrafast spectroscopy to medicinal chemistry and biology – but all with a shared interest in the use of light.

Dalton Discussions are an excellent forum for scientists to present and discuss their work, allowing an invaluable exchange of views and ideas. Researchers submit their abstracts to the Scientific Committee, then selected authors are chosen to present their work at the meeting. Prior to the meeting the authors submit their work as an article, which is then peer reviewed and circulated amongst the participants. At the meeting itself the author has 5 minutes to summarise their article and then the floor is opened to questions and debate – the real focus of Dalton Discussions.

The call for papers is now open, submit your oral abstract now to be part of Dalton Discussions 13.

Key note speakers:

Professor Majed Chergui, Switzerland
Professor Luisa de Cola, Germany
Professor Richard Eisenberg, USA
Professor Peter Ford, USA

The key themes of the meeting have been identified as solar energy, energy and electron transfer, applications of strongly emissive complexes and bond breaking and isomerisation.

Deadlines:

Oral abstract deadline 9 October 2011
Poster abstract deadline 6 July 2012
Early bird registration deadline 6 July 2012
Standard registration deadline 3 August 2012

Visit the DD13 website for more information.

Hot Article: Leonard Lindoy’s latest metallosupramolecular research

Read Leonard Lindoy’s latest supramolecular host-guest formation research in this Dalton Transactions Hot article.

Lindoy’s group make helicates and tetrahedral Ni and Fe host complexes from quaterpyridine ligand derivatives, and look how they can control which products they get. They are particularly interested in the cavity volumes of the tetrahedral cages they make, and hope in the future to look at the host-guest chemistry of the cages with the largest cavities.

Hot Article: Electrochemistry in metal-organic frameworks

In this Dalton Transactions Hot article Andrew Burrows and Frank Marken and colleagues from the University of Bath make MOFs of zincII and aluminiumIII dicarboxylate frameworks with covalently attached ferrocene functional redox groups.

Burrows uses post-synthetic modification to attach the ferrocenyl groups to the frameworks using an amine to amide functional group interconversion. The metal-organic frameworks they made were found to have novel redox active properties, which is an interesting development in the search for designer-electocatalysts.

Hot Article: Colin Raston and cobalt cage molecules

In this Dalton Transactions Hot article Colin Raston and collaborators from the University of Western Australia and the University of Malaya look at CoIII sarcophagine-type cage molecules.

They do both a solid state and solution study of how [Co(diCLsar)]3+ and [Co(HONOsar)]3+, form host–guest inclusion complexes with calixarenes.

As Professor Raston served on the advisory board, this work will be included in the 40th Anniversary volume of Dalton Transactions, celebrating the journals history.
