Applications of Diphosphines in Radical Reactions

Abstract Recently, the importance of organophosphorus compounds in organic chemistry has increased. Diphosphines are an attractive source of phosphorus containing two phosphorus groups, which can theoretically be introduced into a carbon framework with high atom economy. There are several diphosphine derivatives, which are closely related to diphosphines, but their reactivities are completely different. In this Minireview, we describe various phosphination reactions with diphosphines and their derivatives under radical conditions.
