摘要: 近年来,有关相转移催化维悌希反应的报道大都限于烷基三苯季鏻盐的研究[1-4],对于带功能基的烷基三苯基季鏻盐的相转移维悌希反应报道甚少[5]。相转移疆悌希反应在有机合成中的应用,尤其是对活性物质(如昆虫性信息素)的合成是非常有意义的。

Abstract: This paper describes the PTC Wittig reaction of ω-hydroxyl alkanyl triphenyl phosphoniurn bromide (Ph3P+ (CH)2OHBr,n=10,11) and aliphatic aldehydes(n-hexanal,n-pcntanal) with different solvents and bases. The optimum reaction conditions which can give high yield (80%) and good isomer ratio (Z:E=90:10)are reported. The method appeared convcnient for synthesizing insect sex pheromones.
