Procedure

A solution of 3-chloro-5-(trichlorovinyl)toluene (7.56 g) and dibenzoyl peroxide (0.5 g) in 250 ml of benzene was heated at reflux. N-Bromosuccinimide (6.04 g) was added in portions and the reaction mixture stirred at reflux for 3 hours. The mixture was then evaporated and the residue titurated with hexane (200 ml). The precipitated succinimide was removed by filtration and washed with hexane (2×25 ml). The hexane was concentrated and the residual oil (10.1 g) chromatographed on silica with petroleum ether as eluant. The column afforded 1.39 g of starting toluene, 1.18 g of dibromide, and 6.57 g of the desired benzyl bromide.
