摘要: 梨圆蚧Quadraspidiotus perniciosus是世界性的农业害虫,主要危害苹果、梨树等果树.Gieselmann和Anderson等分离并鉴定出梨圆蚧性信息素为3,7-二甲基-2,7-辛二烯-1-醇丙酸酯(1)和7-甲基-3-亚甲基-7-辛二烯-1-醇丙酸酯(2).1的Z体和E体的比例约为10:1.田间生测发现.1的Z体、E体对雄性蚧虫均有强烈的引诱活性,两者以不同比例混合使用,活性并无明显的降低.

Abstract: Telomerization of isoprene with diethylamine in the presence of palladium dichloride, triphenylphosphine as catalyst produced N, N-(3,7-dimethyl-2, 7-octadienyl) diethylamine isomers, which gave a 12.7% yield of (1b) based on the isomer content under the in situ reaction with sodium prorionate.
