    摘要： An optically active 1,2-bis(dialkylphosphino) benzene derivative represented by the general formula (1) which is suitable as a ligand for a transition metal catalyst in asymmetrical hydrogenation is provided. Also provided is a process for producing such a benzene derivative, and a rhodium metal complex having such a benzene derivative as a ligand which is useful as an asymmetric catalyst for use in asymmetrical hydrogenation. (where R1 denotes a straight or branched alkyl group having 2-6 carbon atoms, and each of the asterisks denotes an asymmetric phosphorus atom).
