Olefin metathesis, Nobel Price wining technology in 2005 with Dr. Robert Grubbs, Dr. Richard Schrock and Dr. Yves Chauvin, is based on the exchange of Alkenes fragments (olefins) by the separation and the regeneration of carbon-carbon double bond.
Development of a new generation of high performance polymers, synthesis of complex pharmaceutical molecules, innovative and cost-effective synthesis pathway,... olefin metathesis combines many advantages and as such is a perfect exemple of what Green Chemistry can achieve.
Polymetallic catalysis is based on the use of different metals in a chemical reaction. Like in a team, each metal displays its own specific properties. Polymetallic catalysts combine these metals to create cooperativity effects.Thanks to this synergy, polymetallic catalysis is more efficient than conventional monometallic catalysts.
The unique properties of polymetallic complexes have long been recognized by Nature, which uses them as enzymes cofactors to perform some of the most difficult reactions, while being in very soft reaction conditions, at ambient temperature and pressure. Researchers at Demeta design polymetallic catalysts by bringing metal centers in close proximity through tailor-made molecular architectures, to create powerful metal-metal interactions. Thanks to these unique cooperative properties, Demeta’s polymetallic catalysts work in eco-friendly conditions, with high productivity and selectivity, outperforming conventional catalysts.
