Abstract: 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 1H NMR.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.

Key words: Phosphorus-containing carbanions, Phase transfer catalysis, Wittig-Horner reaction
