Abstract
Styrenes were alkylated with alkyl tosylates, sulfates and bromides in the presence of a zirconocene catalyst and (BuMgCl)-Bu-n in THF. By t he use of this reaction; primary and secondary alkyl groups can be int roduced regioselectively at the benzylic carbon of styrenes to give al pha-substituted ethylbenzenes.
