A number of α-bromocyclopropyllithium reagents have been prepared at low temperature (−90° to −100°) in THF or THF/Et2O medium by reaction of n-butyllithium with the respective gem-dibromocyclopropane. Reactions of these new lithium reagents with concentrated HCl, trimethylchlorosilane, dimethyldichlorosilane, trimethyltin chloride, dimethyltin dichloride, dimethyldichlorogermane, trimethyllead bromide
通过正丁基锂与相应的宝石-二溴环丙烷的反应,已在THF或THF / Et 2 O介质中于低温(-90°至-100°)下制备了多种α-溴环丙基锂试剂。描述了这些新的锂试剂与浓盐酸,三甲基氯硅烷,二甲基二氯硅烷,三甲基氯化锡,二甲基锡二氯化物,二甲基二氯锗烷,三甲基溴化铅,氯化汞和一些其他有机金属卤化物的反应。的一种新的异构化顺式-7-溴-反-7- lithionorcarane到反-7-溴-顺-7- lithionorcarane,通过稍微过量的7,7- dibromonorcarane的存在引起的,进行说明。
