반응 단계
134.5 g (1 mol) of 1-chloro-2,2-dimethyl-butan-3-one were dissolved in 500 ml of ether. 51 ml (1 mol) of bromine were added dropwise at room temperature, while cooling slightly, at a rate such that it was continuously consumed. Thereafter, the solution was stirred into 1,000 ml of ice-water and the organic phase was separated off, rinsed with 250 ml of water, dried over sodium sulphate and distilled. 169 g (80% of theory) of 1-bromo-4-chloro-3,3-dimethyl-butan-2-one of boiling point 95°-106° C./13 mm Hg were obtained. ##STR12##
