The catalysts of formula (II): [Ru(L)m(L')wXY], wherein X and Y represent simultaneously or independently a hydrogen or halogen atom, a hydroxy group, or an alkoxy, carboxyl or other anionic radical, m is 1 or 2, w is 1 when m is 1 and w is 0 when m is 2, L is a phosphino-amine or phosphino-imine bidentate ligand and L' a diphosphine, are useful for the hydrogenation of substrates having a carbon-hetero atom double bond.

L'invention concerne des catalyseurs de formule (II) [Ru(L)¿m?(L')¿w?XY] dans laquelle X et Y représentent simultanément ou indépendamment un atome hydrogène ou halogène, un groupe hydroxy, ou un radical alcoxy, carboxyle ou un autre radical anionique, m est 1 ou 2, w est 1 lorsque m est 1 et 0 lorsque m est 2, L est un ligand bidentate phosphino-amine ou phosphino-imine et L' est une diphosphine. Les catalyseurs précités sont utiles pour l'hydrogénation de substrats dotés d'une double liaison carbone-hétéro-atome.
