IUPAC define hydrogen bond

An IUPAC task group has recently published their recommendations for the definition for the hydrogen bond.

“The hydrogen bond is an attractive interaction between a hydrogen atom from a molecule or a molecular fragment X–H in which X is more electronegative than H, and an atom or a group of atoms in the same or a different molecule, in which there is evidence of bond formation.”

The recommendations continue with a list of experimental and theoretical criteria that can be used as evidence for the presence of the hydrogen bond, and finish with characteristics that are typical of hydrogen bonded systems.

For more information on the task group and to view the provisional recommendation see the IUPAC report.

Nobel Congratulations to Richard Heck, Ei-ichi Negishi and Akira Suzuki

The 2010 Nobel prize for chemistry has been awarded to Professors Richard Heck (University of Delaware, USA), Ei-ichi Negishi (Purdue University, USA) and Akira Suzuki (Hokkaido University, Japan), ‘ for palladium-catalyzed cross couplings in organic synthesis’.

Palladium-catalyzed cross coupling has had, and continues to have, a significant and wide reaching impact on research around the world, as well as in the commercial production of, e.g. pharmaceuticals and molecules for the electronics industry.

On behalf of the Dalton Transactions Editorial Board and Editorial Office, hearty congratulations, Richard, Ei-ichi and Akira!

Read Ei-ichi Negishi’s recent Dalton Transactions Perspective article, A quarter of a century of explorations in organozirconium chemistry, Dalton Trans., 2005, 827-848.

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:

Photoinduced four- and six-electron reduction of mononuclear ruthenium complexes having NAD+ analogous ligands

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.
