Diphenylphosphine
Description
Diphenylphosphine acts as an intermediate in the preparation of diphenylphosphide derivatives, phosphonium salts, phosphine ligands and Wittig-Horner reagents. The presence of hydrogen atom bonded to phosphorus undergoes Michael-like addition to activated alkenes. It is involved in the preparation of 1,2-bis(diphenylphosphino)ethane and (phenyl-(phenylmethyl)phosphoryl)benzene. Further, it is used in the synthesis of aminophosphines and chiral palladacycles with N-heterocyclic carbene ligands as catalysts.
