BIDENTATE CHIRAL LIGANDS FOR USE IN CATALYTIC ASYMMETRIC ADDITION REACTIONS

Compounds of the formula (I), in the form of mixtures comprising predominantly one diastereomer or in the form of pure diastereomers, Z1-Q-P*R0R1 (I) in which Z1 is a C-bonded, secondary phosphine group -P(R)2; in which R is in each case independently hydrocarbon radicals or heterohydrocarbon radicals, or Z1 is the -P*R0R1 group; Q is a bivalent, achiral, aromatic base skeleton, a bivalent, achiral ferrocene base skeleton, an optionally substituted bivalent cycloalkane or heterocycloalkane skeleton, or a C1-C4-alkylene skeleton, and in which base skeletons a secondary phosphine group Z1 is bonded directly to a carbon atom, or, in the case of cyclic base skeletons, directly to a carbon atom or via a C1-C4-alkylene group, and in which base skeletons a P-chiral group -P*R0R1 is bonded directly to a carbon atom, or, in the case of cyclic base skeletons, directly to a carbon atom or via a C1-C4-alkylene group to a carbon atom such that the phosphorus atoms are linked via 1 to 7 atoms of a carbon chain optionally interrupted by heteroatoms from the group of O, S, N, Fe or Si; P* is a chiral phosphorus atom; R0 is methyl or hydroxyl, and R0 is methyl when Z1 is the -P*R0R1 group; and R1 is a C-bonded optically enriched or optically pure chiral, mono- or polycyclic, nonaromatic hydrocarbon or heterohydrocarbon radical which has 3 to 12 ring atoms and 1 to 4 rings and which has a stereogenic carbon atom at least in the α position to the P-C bond; Metal complexes of these ligands are homogeneous catalysts for asymmetric addition reactions, particularly hydrogenations.
