Guy Bertrand

from Wikipedia, the free encyclopedia

Guy Bertrand (* 1952 ) is a French chemist ( organic chemistry ), known for his contributions to the chemistry of carbenes .

Bertrand studied at the University of Limoges and at the University of Montpellier, graduating as an engineer in 1975. He received his doctorate in 1979 from the Paul Sabatier University in Toulouse. As a post-doctoral student he was at Sanofi. He did research in Toulouse for the CNRS (Research Director from 1988, from 1994 1st class and from 2001 Classe exceptionelle). In 2001 he became a professor at the University of California, Irvine , and in 2012 at the University of California, Davis , where he is a Distinguished Professor and directs a joint university research laboratory with the CNRS.

From 1992 to 1999 he was also Maitre de Conference at the École Polytechnique and from 2000 to 2004 he was professor there. In 1998 he was visiting professor at the ETH Zurich.

Bertrand was involved in the discovery of the first persistent carbene in the 1980s, a phosphino-silyl-carbene (1988), in which the carbene is stabilized by neighboring phosphorus and silicon atoms. Three years later, the N-heterocyclic carbenes (NHC) were discovered by Anthony J. Arduengo (1991), which were more suitable because they were cyclic in contrast to the carbenes discovered by Bertrand and colleagues in 1988. They were also available in crystalline form, whereas Bertrand's group had obtained their carbene by flash distillation in vacuo (and could only make it crystalline in 2000). This turned carbene chemistry from an exotic fringe topic into a very active research area with thousands of publications. They were used as ligands of transition metal complexes in catalysis and the substances themselves in organic catalysis and also to stabilize other originally unstable compounds such as radicals.

In 2005 he introduced carbenes with only one nitrogen in the vicinity ( CAAC , cyclic alkyl amino carbenes). Like the Arduengo carbenes, they were also cyclical. The first monosubstituted carbene was also initially crystallized in his working group.

He is a member of the Académie des Sciences (2004, corresponding member since 1996), the American Association for the Advancement of Science , the Académie des Technologies, the European Academy of Sciences and the Academia Europaea . He has received the Humboldt Research Award several times . In 1998 he received the CNRS silver medal . In 2010 he received the Grand Prix Le Bel of the French Chemical Society, in 2014 the American Chemical Society Award in Inorganic Chemistry and in 1999 the Prize of the Japan Society for the Promotion of Science. In 2013 he became a Knight of the Legion of Honor .

From 1995 to 2000 he was vice chairman of the European Chemical Society.
