摘  要:亲核性碳负离子与亲电性碳-碳双键的共轭加成反应是形成新碳-碳键的重要方法.含磷碳负离子的共轭加成反应已有报道,但反应一般都是在强碱作用和无水条件下进行,反应条件比较苛刻,如O。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.

关 键 词:含磷碳负离子 共轭加成反应 阴离子
