摘　　要：含磷α－碳负离子的相转移催化Ｗｉｔｔｉｇ－Ｈｏｒｎｅｒ反应刘增勋，刘舜尧（南开大学元素有机化学研究所，天津，３０００７１）关键词含磷碳负离子，相转移催化，Ｗｉｔｔｉｇ－Ｈｏｒｎｅｒ反应Ｗｉｔｔｉｇ－Ｈｏｒｎｅｒ反应是形成碳－碳双键的重要方法，有关它的...This paper reports Wittig-Horner reactions of phosphorus-containing a-carbanions derived from ethoxy carbonylmethyl phenyl phosphonate(Ⅰ) and cyanomethyl phenyl phosphonate(Ⅱ)with aldehydes and ketones by phase-transfer catalysis. The structures of ten compounds were determined by elemental analysis and 1HNMR.It was discussed that(E)-olefines were obtained by the reaction of(Ⅰ) with aldehydes, and that the mixed products of(E) and(Z)-olefins were obtained by the reaction of(Ⅱ)with aldehyde.
