The first synthesis of diethyl α,α- chlorofluorobenzylphosphonates

Starting from a-hydroxyphosphonates, a wide variety of diethyl α,α-chlorofluorobenzylphosphonates have been obtained in pure form in a two-step procedure. The first step was chlorination of a- hydroxyphosphonates with Ph3P and CCl4,

A highly selective synthesis of α-monofluoro- and α-monochloro- benzylphosphonates using eiectrophilic halogenation of benzylphosphonates carbanions

The selective electrophilic monofluorination and monochlorination of a wide variety of diethyl benzylphosphonates have been realized in a one-pot procedure. The monohalogenation was accomplished by intermediate of a benzylic carbanion protected with TMSCl
