실험 절차

17.6 g (0.1 mol) of 1-phenyl-3,3-dimethyl-butan-2-one were dissolved in 100 ml of carbon tetrachloride, 5 ml (0.1 mole) of bromine were added dropwise thereto while stirring and under reflux, and the mixture was heated to the boil for one hour. After cooling, the distilling off the solvent, 25.4 g of 1-bromo-1-phenyl-3,3-dimethyl-butan-2-one of melting point 38°-42° C. were obtained in quantitative yield.
