2-Phenylacetophenone → 2-Bromo-1,2-diphenylethan-1-one

Participants

Reaction Steps

196 g (1 mole) of phenyl benzyl ketone were suspended in 1 liter of carbon tetrachloride. A solution of 51 ml (1 mole) of bromine in 50 ml of carbon tetrachloride were added dropwise, under irradiation (UV), at a rate such that a steady consumption of bromine took place. The solvent was then distilled off in a water pump vacuum. 274 g (quantitative yield) of ω-bromo-ω-phenyl-acetophenone of melting point 48°-50° C. were obtained.
