Abstract: This paper reports the formation of a-carbanions containing phosphorus from ethoxy carbonylmethyl phenyl phosphonate(I) and cyanomethylphenylphosphonate(I) under the conditions of solid-liquid phase tranfer catalysis,and thirteen new compounds synthesized by the conjugated addition between the carbanions and unsaturated carboxylates,as well as unsaturated cyanides.The structures of the new compounds were determined by elementary analysis and 1H NMR.The synthetic method is considered convenient and practicable for introducing desired functional groups through the conjugated addition of the compounds containg phosphorus as the acceptors under mild conditions.

Key words: Carbanion containg phosphorus, Phase transfer catalysis, Conjugated addition
