Poster prize winner at EuCOMC 2011 in Toulouse

I am delighted to announce that Christian Färber from Germany was the winner of the Dalton Transactions Poster Prize at the recent EuCOMC meeting in beautiful Toulouse. Christian is based at the University of Kassel in Germany in the group of Ulrich Siemeling.

The title of Christian’s winning poster was: Zwitterionic Nitron as an Instant N-Heterocyclic Carbene

  1. Christian Färber says:

    Zwitterionic Nitron has been known for more than 100 years and found numerous applications in different fields of chemistry. It is (cheaply) commercially available and for its fundamental nature it has been considered in several publications because of its betainic/mesoionic structure.

    My achievement with respect to Nitron was simply getting aware of its true nature: As a solid, Nitron exists as a mixture of isomers but in solution I realized its existence as an N-heterocyclic carbene. This conversion is possible due to a tautomeric shift. Altogether I probably invented (or discovered) the simplest procedure to synthesise NHC´s starting from commercially available materials: Dissolve Nitron in any organic solvent and make carbene chemistry ! Therefore I considered Nitron to be an instant N-heterocyclic carbene and I named the carbene tautomer Nitronylidene.

    This and more I presented at the EuCOMC meeting in Toulouse which I enjoyed very much.
    There were many great talks and I learned a lot studying great posters (this helps me developing new ideas). My funniest experiences during the poster session were the visits of PhD students who were looking for simple carbene procedures. They asked me what they would have to do to obtain this carbene. I always answered: Buy it !

    I am working in the group of Ulrich Siemeling in Kassel, Germany. When we started carbene chemistry more than three years ago, we developed a big interest in the nature of the carbene carbon atom. We found, that N-heterocyclic carbenes can do a lot more than only binding to a transition metal…If you are interested, please enjoy the above cited papers.
