2-Chloro-4-fluorobenzyl bromide Use and Manufacturing

A mixture of 77.6 g (0.54 mol) of 2-chloro-4-fluorotoluene, 95.6 g(0.54 mol) of N-bromosuccinimide, 1 g of benzoyl peroxide, and 1000 ml of carbon tetrachloride were refluxed for 3 h. The resulting mixture was cooled to room temperature and then filtered through a glass frit (G3). The precipitate was additionally washed with 3 x 100 ml of carbon tetrachloride. The combined filtrate was evaporated to dryness. Fractional distillation of the residue gave pure title product, bp 97-99°C/10 mm Hg. Yield 106 g (88percent).Anal. calc. for C1-(Bromomethyl)-2-chloro-4-fluorobenzene
