METHOD FOR PRODUCING AXIAL ASYMMETRIC COMPOUNDS, INTERMEDIATES FOR PRODUCING THE SAME, COMPLEXES OF TRANSITION METALS WITH NOVEL AXIAL ASYMMETRIC COMPOUNDS AS THE LIGANDS, CATALYSTS FOR ASYMMETRIC HYDROGENATION, AND CATALYSTS FOR FORMING ASYMMETRIC CARBON-CARBON BONDS
The invention provides a metal complex comprising a ligand and a metal. The ligand is an aminophosphine compound represented by the following formula (1) ;Each Ar represents an aryl group optionally substituted with a halogen atom, a lower alkyl group having 1 to 4 carbon atom or an alkoxy group, both Ar's being same or different with each other. R1 and R2 represent hydrogen atom, a cycloalkyl group having 5 to 7 carbon atoms, or an alkyl group having 1 to 6 carbon atom optionally substituted with a halogen atom, a lower alkoxy group or phenyl group, with R1 and R2 being same or different with each other. Alternatively, one of R1 and R2 is hydrogen atom and the other is COR3 (R3 represents a cycloalkyl group having 5 to 7 carbon atoms, a lower alkyl group having 1 to 6 carbon atom optionally substituted with a halogen atom, a lower alkoxy group or phenyl group, a substituted or unsubstituted phenyl group, or a lower alkoxy group having 1 to 6 carbon atom optionally substituted with a cycloalkyl group having 5 to 7 carbon atoms, a halogen atom, a lower alkoxy group or phenyl group) or SO2R4 (R4 represents a cycloalkyl group having 5 to 7 carbon atoms, an alkyl group optionally substituted with a halogen atom, a lower alkoxy group or phenyl group, or substituted or unsubstituted phenyl group). n represents 0. The metal is rhodium, ruthenium, iridium or nickel.
