Description

A technological revolution 

In 2005, Dr. Robert Grubbs, Dr. Richard Schrok and Dr. Yves Chauvin were awarded the Nobel Prize in Chemistry for olefin metathesis. The discovery has seen many applications since the 90s, thanks to its selectivity and its ability to make complex chemical reactions easy.

Olefin metathesis entails the redistribution of alkene fragments (olefins) by the scission and regeneration of carbon-carbon double bonds. The technology has become a key element in synthesis strategies for the construction of many organic compounds and the production of materials such as polymers and fine chemicals

Description

A new generation of catalysts 

Marc Mauduit, co-founder of Demeta, joined the Ecole Nationale Supérieure de Chimie in Rennes, where he began his research, in 2001. His work led to the discovery of this new generation of olefin metathesis catalysts.
