Bromine → 1-Bromo-4-(4-chlorophenoxy)-3,3-dimethylbutan-2-one

Participants

Reaction Steps

26 g (0.159 mol) of 1-(4-chlorophenoxy)-2,2-dimethyl-butan-3-one were dissolved in 300 ml of chloroform and 25.5 g (0.159 mol) of bromine were added dropwise, at 20° C. at such a rate that decoloration took place continuously. After completion of the addition, the mixture was stirred for 30 minutes at room temperature and was then concentrated by distilling off the solvent in vacuo. 48.5 g (quantitative conversion) of 1-bromo-4-(4-chlorophenoxy)-3,3-dimethylbutan-2-one of boiling point 150°-160° C./0.19 mbar, were obtained. ##STR13##
