Dalton Transactions International Symposium a resounding success!

The successful 2nd Dalton Transactions International Symposium took place in China last week.  The Symposium, organised as a joint venture between Dalton Transactions and the RSC International Programme, took place over two days, in two venues in Asia. The first day of the Symposium (16th November) was organised as part of the 11th Conference on Solid State Chemistry and Inorganic Synthesis, held in Shanghai.  Professor Jiesheng Chen from the host university, Shanghai Jiao Tong University, was the local organiser, and his meticulous planning ensured the smooth running of the event.

Professor Annie Powell (Karlsruhe Institute of Technology, Germany) began the day with an account of her work on the use of coordination chemistry to construct nanostructured materials from a bottom up approach.  Annie was followed by Professor Song Gao (Peking University, China), who introduced some of his work on single molecule magnets.  Professor Hiroki Oshio (University of Tsukuba, Japan) then took us up to lunchtime with his inspiring presentation on multinuclear magnetic complexes.  After lunch, Professor Yong Zhao presented the work he has been doing with Professor Lei Jiang at the Chinese Academy of Sciences. Professor Lee Cronin (University of Glasgow, UK) ended the day with a fascintating presentation on his work on adaptive inorganic materials.

Three of the speakers (Professors Cronin, Oshio and Powell) then travelled to Hong Kong, for the second day of the Symposium (18th November).  Hosted by the University of Hong Kong, the speakers were joined by three local speakers, Professor Vivian Yam (University of Hong Kong) , who gave a fascintating presentation on her elegant research on  photofunctional metal-based molecular materials , Professor Zuowei Xie (Chinese University of Hong Kong) , who described his work with hypervalent carbon in metal-carbon bonds and Professor Wai Yeung Wong (Hong Kong Baptist University) ended the day with his presentation on the use of organometallic compounds for OLEDs .

Hot Article: Cheap iron catalysts enantioselective?

Richard Catlow and co-workers, based at the University College London, have used DFT to reveal new insights into the catalytic properties of cheap Fe complexes and have compared them to their more expensive and toxic Ru counterparts. The group look spectifically at these catalysts in ketone/alcohol hydrogen transfer reaction and show that the Fe compounds could be viable in these pharmaceutically important reactions. Read this group’s recent Dalton Transactions Hot Article for more info.

Call for papers: d0 Organometallics in Catalysis

Dalton Transactions is delighted to announce an upcoming themed issue entitled ‘d0 Organometallics in Catalysis’, with guest editors John Arnold and Peter Scott. It is our pleasure to invite you to contribute to this issue.

Why is this themed issue important?

The discovery of homogeneous catalysts for Ziegler-type polymerisation of olefins led to immense interest in the synthesis of well-defined early transition metal (TM) complexes, starting with metallocenes but extending into a vast array of new complexes with a broad spectrum of supporting ligand environments. This led to synergistic growth in the application of such complexes to organic transformations, both as catalysts and stoichiometric agents. These Lewis acidic metal centres are capable of mediating migratory insertion reactions, often at immense rates. Reactions involving early TM-element multiple bonds have been known for some time but are becoming increasing important. Controlling the coordination sphere of these compounds for chemo- and stereoselective processes continues to be a challenge, but with the appropriate combination of metal center and supporting ligand environment, superb selectivities in demanding transformations are possible. Recent highlights include hydroelementation reactions involving B-H, C-H, P-H and S-H bonds and small molecule activation.

Deadline for Submission: 18th January 2011

With this themed issue focussing on d0 organometallics, we are aiming to highlight contributions from leading experts of the field.  All types of manuscript, Communications, Full Papers, Perspectives and Frontiers, will be considered for publication. The issue will include articles from Doug Stephan, Robert Bergman and Laurel Schafer.

The manuscript should be prepared according to the format for regular articles and will be subjected to the normal refereeing procedure.  Please indicate on submission that your manuscript is intended for this themed issue. Submit your manuscript for the themed issue online now using our submission system!

We would be delighted to hear from you at dalton-rsc@rsc.org if you are interested in contributing to this themed issue or if you would like any further info.
