Treatment of methylarenes with 1,3-dibromo-5,5-dimethylhydantoin or N-bromosuccinimide and a catalytic amount of 2,2′-azobis(isobutyronitrile) followed by a reaction with a nucleophile, such as benzoic acid, p-toluenethiol, sodium p-toluenesulfinate, aqueous dimethylamine, or succinimide, provides the corresponding benzylated products in good yields.
