Phenoxy-2-propanone (0.10 mol), N-bromosuccinimide (0.10 mol) and a catalytic amount of 2,2'-azobis(2-methylpropionitrile) were stirred together in tetrachloromethane (100 ml) at 80° C. for 61/2 hours. The solvent was distilled off and the residue distilled under vacuum to give (1-bromo-2-oxopropyl) oxybenzene. Yield: 10.4 g (45 %), b.p. 66°-68° C./0.01 mm Hg. 1H NMR (CDCl3, δ): 2.50 (s, CH3) 6.40 (s, --CHBr--), 6.9-7.5 (5H, Ph).
