Benzoyl Peroxide → 5-Bromo-2-(bromomethyl)-1,3-dichlorobenzene

Participants

Reaction Steps

Heat to reflux a solution of 5-bromo-1,3-dichloro-2-methylbenzene (97 mg, 0.40 mmol), N-bromosuccinimide (76 mg, 0.425 mmol) and benzoyl peroxide (16 mg, 0.06 mmol) in CCl4 (5 mL) for 3 hours under N2. Cool the reaction to room temperature and concentrate to an orange residue. Purify the residue by silica gel chromatography eluting with hexanes to afford 112 mg (87%) of the product as white crystals.
