Claim:
Compounds of the formula (I) in the form of a mixture of predominantly one diastereomer or in the form of a mixture of pure diastereomers, Z 1 -Q-P*R 0 R 1 (I), wherein: Z 1 is a C-bonded, secondary phosphine group of the formula —P(R) 2 , wherein R is a hydrocarbon radical or O-atom(s)-containing heterohydrocarbon radical having 1 to 18 carbon atoms and optionally substituted by C 1 -C 6 -alkyl, trifluoromethyl, C 1 -C 6 -alkoxy, trifluoromethoxy, (C 1 -C 4 -alkyl) 2 amino, (C 6 H 5 ) 3 Si, (C 1 -C 12 -alkyl) 3 Si or halogen; Q is selected from the group consisting of: (i) an optionally substituted achiral aromatic group, wherein the achiral aromatic group is bonded directly to Z 1 through a carbon atom of the achiral aromatic group, or optionally bonded to Z 1 through a C 1 -C 4 -alkylene group, and bonded directly to P*R 0 R 1 through a carbon atom of the achiral aromatic group, or optionally bonded to P*R 0 R 1 through a C 1 -C 4 -alkylene group, which is optionally interrupted by a heteroatom selected from the group consisting of O, S, N, Fe and Si, (ii) an optionally substituted achiral ferrocene group, wherein the achiral ferrocene group is bonded directly to Z 1 through a carbon atom of the achiral ferrocene group, or optionally bonded to Z 1 through a C 1 -C 4 -alkylene group, and bonded directly to P*R 0 R 1 through a carbon atom of the achiral ferrocene group, or optionally bonded to P*R 0 R 1 through a C 1 -C 4 -alkylene group, which is optionally interrupted by a heteroatom selected from the group consisting of O, S, N, Fe and Si, (iii) an optionally substituted cycloalkane or heterocycloalkane group, wherein the cycloalkane or heterocycloalkane group is bonded directly to Z 1 through a carbon atom of the cycloalkane or heterocycloalkane group, or optionally bonded to Z 1 through a C 1 -C 4 -alkylene group, and bonded directly to P*R 0 R 1 through a carbon atom of the cycloalkane or heterocycloalkane group, or optionally bonded to P*R 0 R 1 through a C 1 -C 4 -alkylene group, which is optionally interrupted by a heteroatom selected from the group consisting of O, S, N, Fe, and Si, and (iv) an optionally substituted C 1 -C 4 -alkylene group; P* is a chiral phosphorus atom; R 0 is hydroxyl; and R 1 is a C-bonded optically enriched or optically pure chiral, mono- or polycyclic, nonaromatic hydrocarbon ring, or tautomers thereof.
