Abstract

Résumé The action of n-BuLi in THF at low temperatures on diethyl methylchlorophosphonates gives the corresponding carbanion, which treated by CCl 4 generates the reagent (C 2 H 5 O) 2 P ( O) CCl 2 Li. The stability of this last compound has been studied in presence of lithium salts. Some coupling reactions with various alkylating reagents are described.
