摘要
本文报道采用间苯氧基苯甲醛与亚硫酸氢钠的加成物在碱性条件和相转移催化剂的存在下,直接与二氯菊酸酰氯及氰化钠反应,生成一种高效低毒和杀虫谱广的拟除虫菊酯,即氯氰菊酯。
This Paper studies new synthetic method for cypermethrin.Cypermethrin may be prepared the action of 3-(2,2-dichlorovingl)-2,2-dimethylcyclopr- opanecarboxylyl chloride,bisulphite compound,sodium,cyanide and sodium carbonate in the presence of phase tranfer catalyst.This method has the characteristices of a mild reaction condition,a short period of time for reaction and a good yield.It is a convenient means of industrial production of cypermethrin.
