AMINE-SUBSTITUTED DIPHENYLDIPHOSPHINES AND THE USE THEREOF IN METAL COMPLEXES FOR ASYMMETRIC ADDITION REACTIONS

摘要

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.
