摘    要:以对叔丁基苯乙腈为原料,经酯化、酯交换得到中间体2-(4-叔丁基苯基)-氰基乙酸(2-甲氧基)乙基酯(Ⅰ);邻三氟甲基氯苯发生格氏反应后,通入二氧化碳得到邻三氟甲基苯甲酸,经氯化亚砜氯化得到中间体邻三氟甲基苯甲酰氯(Ⅱ)。中间体2-(4-叔丁基苯基).氰基乙酸(2.甲氧基)乙基酯(Ⅰ)在碳酸钠催化下与中间体邻三氟甲基苯甲酰氯(Ⅱ)在相转移催化下得到目的产物丁氟螨酯,总收率43.1%(以对叔丁基苯乙腈计)。

关 键 词:杀螨剂  丁氟螨酯  合成

Abstract:The intermediate( Ⅰ ) of methyl 2-(4-tert-butylphenyl)cyanoacetate was synthesized by esterification and transesterification reaction of 4-tert-butylphenylacetonitrile with dimethyl carbonate and ethylene glycol monomethyl ether successively. 2-trifluoromethyl benzonic acid was prepared by Grignard reaction of2-chlorid benzotrifluorid followed by carbonation, then it was chlorinated by SOC12 to give the intermediate(Ⅱ)2-trifluoromethylbenzoyl chloride. Under the catalytic of Na2CO3, the intermediate( Ⅰ )reacted with(Ⅱ)to give the target production of cyflumetofen. The total yield is 43.1%(calculation on 4-tert-butylphenylacetonitrile).
Keywords:acaricide  cyflumetofen  synthesis
