Countdown to the Dalton Transactions 40th Anniversary!

Dalton Transactions celebrates the publication of its 40th volume in 2011! Since its first issue was published in 1972, Dalton Transactions has gone from strength to strength with growth in published articles of 122% over the last five years alone and an impact factor now at 4.1 – above 4 for the first time!

During 2011 we have lots of exciting events planned to celebrate…..look out for our special 40th Anniversary issue which will feature articles by Editorial and Advisory Board members ‘old and new ‘ and also our Anniversary Perspective articles from our Editorial Board member.

We will also publish a series of Anniversary Editorials compiled by members of the inorganic and organometallic community charting Dalton Transactions‘ progress in the last 40 years. In addition, many more activities are planned so keep your eyes peeled here on the Dalton Transactions Blog 40th Anniversary Category for more info throughout the year. I would like to invite everyone to provide us with your suggestions for how to celebrate the journal’s anniversary – if you have an idea, why not post it as a comment on the blog?

In anticipation of the beginning of our Anniversary year we have turned to Top of the Pops for inspiration and the Top 40 cited Dalton Transactions articles according to ISI* will be FREE to read until the end of January 2011. What are they you may ask….let the countdown begin…

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.
