摘要：
Compounds where a solid carrier material which contains diphosphine rhodium or iridium complexes fixed on the surface thereof, of which the carrier material has the formula IV or IVa: ##STR1## wherein Y denotes two monoolefin ligands or a diene ligand, M is Ir(I) or Rh(i), Z is --Cl, --Br or -I, A.crclbar. is the anion of an oxyacid or complex acid, T is a solid carrier material, r is 0, 1 or 2, and R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are as defined in claim 1. These materials are heterogeneous and separable catalysts for the asymmetrical hydrogenation of prochiral compounds containing carbon double bonds or carbon/hetero atom double bonds, for example ketones and imines.
