Hot Article: Solving the puzzle of Cu-catalyzed crosscoupling

In their Hot Article, Solà, Stahl, Ribas and co-workers shed mechanistic light on the pharmaceutically important Cu-catalyzed Ullmann–Goldberg-type crosscoupling chemistry. Until now, fundamental knowledge of the mechanism of these reactions was still lacking. Find out more in this Dalton Transactions paper.

Hot Article: Degradation powering oxidation catalysts

In their exciting Dalton Transactions Hot Article, Wesley Browne, Ben Feringa and colleagues show that pyridine-2-carboxylic acid plays an unexpected role in manganese based oxidation catalysis. The group show that, though catalyst degradation is typically considered as a cause of catalyst deactivation, in this case in situ ligand degradation actually results in a highly active oxidation system.

Hot Article: molecular system for solar energy to fuel conversion

In this hot article the authors describe the synthesis and the characterizations of two new ruthenium complexes exhibiting proton coupled four- or six-electron photoreduction in solution in presence of a sacrificial electron donor.

These complexes are among very few systems where stepwise multi-photon absorption are accompanied by multi-reducing equivalents storage and could be useful to convert solar energy into fuels:

Dalton Discussion 12: Catalytic C-H and C-X Bond Activation

The stunning city of Durham provided a picturesque setting for the 12th Dalton Discussion meeting (DD12) highlighting the highly topical field of Catalytic C-H and C-X Bond Activation. The meeting was a joint venture between the RSC’s Dalton and Organic Divisions. The organising committee for the discussion meeting, consisting of Phil Dyer, Ian Fairlamb, Sue Gibson (Organic Division), Peter Scott (Dalton Division) and chaired by Todd Marder, must be congratulated for a fantastic meeting rife with lively debate and high quality chemistry.  

The conference brought together the organic, organometallic, and inorganic (coordination chemistry) communities from academia and industry to consider the current state of the art, the development and future of late metal-catalysed cross-coupling strategies of C-X and C-H bonds. The conference dinner took place in the unique surroundings of Durham Castle and the discussion continued long into the night!

Obviously, discussion was a central element to this meeting both at the poster session and in the sessions themselves. Congratulations to Anne Germeroth (University of Edinburgh) for winning the Dalton Transactions Poster Prize with an excellent poster entitled ‘Reversible reactions across the M-C bond of lanthanide NHC complexes to form new N-E and C-E bonds’.

Congratulations also to the other poster prize winners at the meeting: Toritse Bob-Egbe (Imperial College London) who won the inaugural Catalysis Science & Technology Poster Prize, Julien A. Panetier (Heriot-Watt University) and Amanda Jarvis (University of York).

 Look out for the DD12 themed issue which will be published as issue 43 Dalton Transactions at the end of October 2010. More information about the meeting itself can be found at the RSC Events webpage.


Have you any ideas for possible future topics for Dalton Discussion meetings? If so we’d be delighted to hear them, you can email us at dalton-rsc@rsc.org.
