Abstract

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 TMSCl followed by halogenation with an electrophilic halogenating reagent.

A highly selective synthesis of α-monofluoro-and α-monochlor...
