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.
Our new generation metathesis catalysts are cost-competitive, extremely selective and open up a whole new range of possibilities, from polymers (Ring Opening Metathesis Polymerization), to complex molecules such as flavors and fragrances (Ring Closing Metathesis), pheromones and pharmaceutical ingredients.
We design catalysts that specifically fit your needs, while guaranteeing reduced costs, higher quality and a lower environmental footprint.
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.
