Various functionalized aryl and heteroaryl aluminum reagents were obtained by performing IâLi or BrâLi exchange reactions with the corresponding unsaturated organic halides in the presence of i-Bu2AlCl. By means of an appropriate catalyst, the resulting new aluminum species were directly acylated, allylated or arylated. 1,4-Michael additions to enones have also been achieved.
通过在i-Bu2AlCl存在下对相应的未饱和有机卤化物进行I-Li或Br-Li交换反应,获得了多种功能化的芳基和杂芳基铝试剂。借助合适的催化剂,所得的新铝物种被直接酰基化、烯丙基化或芳基化。同时,还实现了对烯酮的1,4-迈克尔加成反应。
