Reaction of Trichloro(o-phenylenedioxy)phosphorane with Four-Coordinate Phosphorus Esters

Abstract

Reactions of trialkyl phosphates and dialkyl alkenylphosphonates with trichloro(o-phenylenedioxy)phosphorane result in selective replacement of one alkoxy group on the phosphorus by a chlorine atom. Alkylphosphonates react with trichloro(o-phenylenedioxy)phosphorane to give alkyl alkylphosphonochloridates as the major products and small amounts of alkylphosphonic dichlorides
