N-bromobutanimide → 4-Bromomethyl-4'-nitrobenzophenone

Participants

Reaction Steps

Benzoyl peroxide (0.012 g) was added to a mixture of 4-(4-methylbenzoyl)-nitrobenzene (1.20 g) and N-bromo succinimide (0.89 g) suspended in carbon tetrachloride (63 mL). The reaction mixture was refluxed under argon for 4 hours while illuminated with an incandescent lamp. The mixture was filtered, and the yellow solution containing the crude product was evaporated, chromatographed on silica gel, eluting with hexane/ethyl acetate, to give 4-(4-bromomethylbenzoyl)-nitrobenzene (1.79 g, 81%) as a white solid, m.p. 112.7-113.1° C.
