Abstract

A convenient method was developed for the selective synthesis of chloromethylbenzylphosphonium salts (2a, b) or phenylenediphosphonium salts (3a,b) based on the reaction of dichloroxylenes (1a or 1b)) with phosphines.. The monophosphonium salt was selectively obtained in toluene and the diphosphonium salt was obtained in DMF.
