実験手順

97 g (0.4 mol) of 1-(4-chlorophenylmercapto)-2,2-dimethyl-butan-3-one were dissolved in 400 ml of carbon tetrachloride, and 64 g (0.4 mol) of bromine were added dropwise in the course of 30 minutes. The mixture was subsequently stirred at room temperature for 1 hour and was then concentrated by distilling off the solvent. 127 g (99% of theory) of crude 1-bromo-4-(4-chlorophenylmercapto)-3,3-dimethyl-butan-2-one were obtained as a yellowish oil, which was further reacted directly.
