Phenyldioxaborolane promoted synthesis of bisphosphine compounds

Bisphosphine compounds have a wide range of applications. In this paper, we reported that bisphosphine compounds could be prepared in moderate to good yields from dialkyl acylphosphonates under mild conditions in the presence of phenyldioxaborolane and potassium hydroxide via a C–P bond cleavage and a subsequent 1,2-migration of phosphoryl group.
