The mixture of triphenylphosphine (PPh3) and 2,3-dichloro-5,6-dicyanobenzquinone (DDQ) as a neutral system has been used for the preparation of various types of diethyl α-bromo, α-iodo and α-azidophosphonates from their corresponding diethyl α-

Starting from diethyl benzylphosphonates, a wide variety of diethyl α- monofluoro, chloro, bromo and iodobenzylphosphonates have been obtained in pure form by a one-pot procedure. This high yielding method implies the intermediate protection of the benzyl anion with TMSCI followed by halogenation with an electrophilic halogenating reagent.
