4-chloro-3,3-dimethylbutan-2-one

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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, with slight cooling, at a rate such that the bromine was steadily consumed. The solution was then 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. was steadily consumed the organic phase was separated off rinsed with 250 ml of water dried over sodium sulphate distilled
