reported. The alkyl groups were introduced by alkylation of phosphines to form phosphonium salts. The “de-arylation” of phosphonium salts was achieved by C–P activation and transfer hydrogenation with homogeneous or heterogeneous Pd (0) catalysts. With this method, a series of trivalent phosphines were prepared from commercially available triarylphosphines. A chiral monophosphine ligand could be prepared
