Abstract

Abstract Starting from α-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 α-hydroxyphosphonates with Ph 3 P and CCl 4, while the second step was fluorination with N-fluorobisbenzenesulfonimide.
