The Michael-type reaction of copper-catalyzed trialkylaluminium reagents with α,β-unsaturated carbonyl compounds is a useful and simple procedure for the transfer of hydrocarbon substituents. The scope of this process and the effect of chlorotrimethylsilane as additive were investigated. Preparatively useful results were generally obtained for enones even with higher organoaluminium reagents, whereas
铜催化的三烷基铝试剂与α,β-不饱和羰基化合物的迈克尔型反应是转移烃取代基的有用且简单的方法。研究了该方法的范围以及氯三甲基硅烷作为添加剂的作用。即使使用更高的有机铝试剂,对于烯酮也普遍获得了制备有用的结果,而与α,β-不饱和醛的反应仅限于三甲基铝的使用。
