ABSTRACT:
A process for producing a biarylphosphine compound is disclosed. The process has a step of subjecting a biarylsulfonate compound to coupling reaction with a hydrogen-phosphine compound in the presence of a catalyst and an organic strong base to obtain a biarylphosphine compound. As the catalyst, preferably used is a nickel compound or a palladium compound. As the organic strong base, preferably used is 1,8-diazabicyclo[5.4.0]undecene-7 (DBU).
