Claim:
A process for producing a hydrogenated compound of an unsaturated compound, which comprises subjecting an unsaturated compound to a homogeneous hydrogenation in the presence of a catalyst comprising a chiral copper complex having a chiral ligand for homogeneous hydrogenation, wherein the catalyst comprises a phosphorus compound represented by the formula (41): PR 151 3 (41) wherein three R 151 s are same or different and represent a hydrogen atom, a hydrocarbon group having 1-20 carbon atoms, a 3- to 8-membered heterocyclic group having 2-14 carbon atoms and 1-3 heteroatoms selected from the group consisting of a nitrogen atom, an oxygen atom and a sulfur atom, said hydrocarbon group and said heterocyclic group being substituted or unsubstituted, an optionally substituted alkoxy group, an optionally substituted aryloxy group, an optionally substituted aralkyloxy group, an amino group or a substituted amino group; and an optically active diphosphine compound, wherein, when the hydrocarbon, heterocyclic group, alkoxy group, aryloxy group, aralkyloxy group, or amino group is substituted, the substituent is selected from the group consisting of an alkyl group having 1 to 20 atoms, an alkenyl group having 2 to 20 carbon atoms, an alkynyl group having 2 to 20 carbon atoms, an alkadienyl group having 4 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an aralkyl group having 7 to 20 carbon atoms, an aliphatic heterocyclic group having 2 to 14 carbon atoms, an aromatic heterocyclic group having 2 to 15 carbon atoms, fluorine, chlorine, bromine, iodine, an halogenated alkyl group having 1 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, an aryloxy group having 6 to 20 carbon atoms, an aralkyloxy group having 7 to 20 carbon atoms, a heteroaryloxy group having 2 to 20 carbon atoms, an alkylthio group having 1 to 20 carbon atoms, an arylthio group having 6 to 20 carbon atoms, an aralkylthio group having 7 to 20 carbon atoms, an heteroarylthio group having 2 to 20 carbon atoms, an acyl group having 1 to 20 carbon atoms, an acyloxy group having 2 to 20 atoms, an alkoxycarbonyl group having 2 to 20 carbon atoms, an aryloxycarbonyl group having 7 to 20 carbon atoms, an aralkyloxycarbonyl group having 8 to 20 carbon atoms, an alkylene group having 1 to 6 carbon atoms, an alkylenedioxy group having 2 to 20 carbon atoms, a nitro group, an amino group, a cyano group, sulfo group, a hydroxyl group, a carboxy group, an alkoxythiocarbonyl group having 2 to 20 carbon atoms, an aryloxythiocarbonyl group having 7 to 20 carbon atoms, an aralkyloxythiocarbonyl group having 8 to 20 carbon atoms, an alkylthiocarbonyl group having 2 to 20 carbon atoms, an arylthiocarbonyl group having 7 to 20 carbon atoms, an aralkyloxythiocarbonyl group having 8 to 20 carbon atoms, a carbamoyl group, a phosphino group and an oxo group.
