Styrenes were alkylated with alkyl tosylates, sulfates and bromides in the presence of a zirconocene catalyst and nBuMgCl in THF. By the use of this reaction, primary and secondary alkyl groups can be introduced regioselectively at the benzylic carbon of styrenes to give α-substituted ethylbenzenes.
在锆茂茂催化剂和正丁基镁的THF溶液中,用甲苯磺酸烷基酯,硫酸盐和溴化物将苯乙烯烷基化。通过使用该反应,伯和仲烷基可以区域选择性地引入苯乙烯的苄基碳,得到α-取代的乙苯。
