摘要
按有机反应的官能团,对EtAlCl2和Et2AlCl催化的有机加成反应的研究进展进行了综述。EtAlCl2和Et2AlCl催化的有机加成反应包括链式加成反应和环加成反应。EtAlCl2和Et2AlCl中的Al3+具有p电子空轨道,Al3+与反应物中某些不饱和键络合,如C=O、C=C、C=N等,也能与催化体系中的某些配体络合,产生协同催化作用。EtAlCl2和Et2AlCl是促进有机加成反应的良好试剂,反应不仅具有较高的产率,而且具有很好的立体选择性。
This EtAlCl2 and Et2AlCl. paper has presented a brief review of the advances of organic addition reaction catalyzed by Organic addition reaction using EtAlCl2 and Et2AlCl as catalysts includes chain addition reaction and cyclic addition reaction. Aluminium of EtAlCl2 and Et2AlCl has empty P orbit, which can not only combine unsaturated bonds such as C = O, C = C and C = N, but also combine some ligands in the catalyzing system to produce cooperative catalysis. Furthermore, EtAlCl2 and Et2AlCl are effective reagent of addition,with high productivity and good solid selectivity.
