摘要
本文报导用2—氯—2—甲基丙烷直接烷基化合成叔丁基二茂铁,无水三氯化铝、2—氯—2—甲基丙烷和二茂铁的摩尔比为0.8:3:1,卤代烷及无水三氯化铝分别同时加入,温度控制在-3～-5℃之间。产物用气相色谱分析,其中叔丁基二茂铁含量在35％以上。
In this paper, the author reports on direet alkylation of ferroeene with tert-butyl chloride to form tert-butyl ferrocene. Molar ratios of AlCl3:tert-butyl chlorides: ferroeene = 0.8:3:1. Reaction temperature was controlled be-tweew - 3^-5℃>anhydrous alumiam chlor:de and tert-butyl ehlonide were added simultaneously. Reaction products were separated by GLC,in which tert-butyl ferrocene is. more than 35%.
