CA 2521635
The invention relates to the 1,1'-diphenyl-2,2'-diphosphines of formulae (Ia), (Ib), having at least one amine substituent in para position to the phosphine group. These novel compounds are ligands for metal complexes that are catalysts for asymmetric addition reactions of prochiral organic compounds and whose catalytic properties can be adjusted in a substrate-specific manner via the substitution of the amino group.
L'invention concerne des 1,1'-diphényl-2,2'-diphosphines comportant au moins un substituant amine en position para, par rapport au groupe phosphine, correspondant aux formules (Ia) et (Ib). Ces composés constituent des ligands pour des complexes métalliques servant de catalyseurs dans des réactions d'addition de composés organiques prochiraux, et dont les caractéristiques catalytiques peuvent être adaptées spécifiquement à des substrats par substitution du groupe amine.
