The title carbanion species are generated from the corresponding α-haloorganosilicon compounds by the action of a catalytic amount of tris(diethylamino)sulfonium difluorotrimethylsilicate and are found to undergo addition to aldehyde carbonyl efficiently at ambient temperature. The synthetic potential of the reaction is demonstrated by application to the synthesis of some insecticides.
由催化量的三(二乙基氨基)ulf二氟三甲基硅酸盐的作用,由相应的α-卤代有机硅化合物产生标题碳负离子,并发现其在环境温度下可有效地加成醛羰基。通过将其应用于某些杀虫剂的合成,证明了该反应的合成潜力。
