| abstract |
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. |
