Procedure

A solution of 4-chloro-3-(trichlorovinyl)toluene (13.77 g) and dibenzoyl peroxide (1.0 g) in 500 ml of benzene was heated at reflux. N-Bromosuccinimide (11.6 g) was added in portions and the resulting mixture stirred at reflux for 1.5 hours (negative KI test). The reaction mixture was concentrated under reduced pressure. The residue was partially dissolved in 300 ml of petroleum ether and the insoluble succinimide removed by filtration. The filtrate was concentrated to give 17.9 g of the benzyl bromide.
