Benzoyl Peroxide → 1-Bromo-4-(bromomethyl)-2-fluorobenzene

Participants

Reaction Steps

A solution of 4-bromo-3-fluorotoluene (21.5 g, 0.114 moles) in acetonitrile (200 ml) is added with N-bromosuccinimide, (NBS; 21.2 g, 0.119 moles). The mixture is refluxed, added with dibenzoyl peroxide (1.4 g, 0.004 moles), refluxed for 3 hour, then cooled at room temperature, and extracted with water. The aqueous phase is discarded, and the organic phase is washed with brine, dried over sodium sulphate, and concentrated under vacuum to give an oil (27.1 g, 90% yield).
