  It is an object of the present invention to provide a novel phosphine compound capable of forming a metal complex useful as a catalyst for various asymmetric synthesis reactions, a production method thereof, and a metal complex comprising the aforementioned compound as a ligand. A 2,2′-bis(dialkylphosphino)biphenyl compound represented by the formula (A-1). A compound represented by the formula (1) is appropriate as a catalyst for an asymmetric synthesis reaction. The biphenyl compound represented by the formula (A-1) can be obtained by subjecting a compound represented by the formula (A-2) to a coupling reaction to obtain an intermediate represented by the formula (A-3), and then subjecting the intermediate to a deboranation reaction. In the formula (A-1), R 1 and R 2 each independently represent a C1-C10 alkyl group, R 3 represents a monovalent substituent, and n represents an integer of 0 to 4. In the formula (1), R 1 represents a C2-C10 alkyl group, R 2 represents an alkyl group containing fewer carbon atoms than R 1 , R 3 represents a monovalent substituent, and n represents an integer of 0 to 4.
