Patent

CA 2311515

The invention relates to penta- and hexa-coordinated ruthenium and osmium complexes with a mono- or bi-cyclic, aromatic heterocyclyl group containing at least one nitrogen atom that is coordinated with the ruthenium or osmium central atom. The novel compounds are excellent catalysts for metathesis reactions and the ring-closure of dienes.

L'invention concerne des complexes de ruthénium et d'osmium penta et hexa-coordonnés comprenant un groupe hétérocyclyle aromatique mono ou bicyclique qui contient au moins un atome d'azote coordonné à l'atome central de ruthénium ou d'osmium. Ces nouveaux composés sont d'excellents catalyseurs des réactions de métathèse et de la cyclisation des diènes.
