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.

Edinburgh celebrates structural chemistry with David Rankin

I was very fortunate to attend the Celebration of Structural Chemistry symposium at the University of Edinburgh recently. The symposium, held on Friday 17th September, marked the retirement of Professor David Rankin. To celebrate this event, and also the significant number of contributions Professor Rankin has published in Dalton Transactions over the years, co-workers past and present were invited by Dr Carole Morrison, Guest Editor, to publish dedicated articles, which were then bound together in a presentation volume for David.

Guest Editor, Dr Carole Morrision presents the collections ofDalton Transactions articles to Professor David Rankin

The symposium consisted of some excellent talks, and the full programme for the afternoon is given below.

Chair: Dr Paul T. Brain, Royal School of Artillery, Salisbury Plain

Prof. Norbert Mitzel, Talk title: “Solid and gas-phase structures: the whole is more than the sum of its parts” University of Bielefeld

Prof. Dwayne Miller. Talk title: “Making the Molecular Movie: first steps”, CFEL – Max Planck Research Department for Structural Dynamics at the University of Hamburg

Prof. Claire Carmalt, Talk title: “Synthesis, structures and CVD studies of metal alkoxides, amides and related compounds” University College London

Dr Paul Lickiss, Talk title: “Structural Studies on Silsesquioxanes (RSiO3/2)n” Imperial College London

Dr Blair Johnston, Talk title: “Molecular Structure, Modelling and the Pharmaceutical Sciences” University of Strathclyde

Dr Derek Wann, Talk title: “Electron diffraction at Edinburgh – looking to the future” University of Edinburgh

Dr Sarah Masters, Talk title: “Canterbury Tales: GED from a different perspective” soon to be University of Canterbury, Christchurch, NZ

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:
