摘要:A process for producing a diphosphine oxide or diphosphonate represented by formula (1) as defined, which comprises treating, with a base, a phosphine compound represented by formula (2) as defined and adding the thus-treated phosphine compound to a nonpolar solvent having an oxidative metal compound suspended therein so as to effect dimerization. The present invention makes it possible to produce, conveniently, in a high yield and safely, a diphosphine oxide or diphosphonate which is an intermediate for producing a diphosphine compound useful as a ligand of a metal complex serving as a catalyst for asymmetric synthesis reaction.
