Compounds of formula III, (see formula III) wherein R6 and R7 signify identical or different secondary phosphino; R8 is - CH2-OH, -CH2-NH2, -CH2-O-B-FU, -CH2-NH2-B-FU, or -O-B-FU; R9 has the same significance as R8 or is C1-C4-alkyl or C1-C4-alkoxy; or R8 and R9 together signify HOCH(CH2-O-)2, H2NCH-(CH2-O-)2, FU-B-OCH(CH2-O-)2 or FU-B-HNCH(CH2-O-)2; B is a bridging group; and FU is a functional group. The compounds may be bonded to inorganic or organic carriers. Their d-8 metal complexes are valuable catalysts for the enantioselective hydrogenation of prochiral organic compounds with carbon multiple bonds or carbon/hetero atom multiple bonds.
