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

Participants

Reaction Steps

36 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. in a manner such that continuous decoloration occurred. When the addition had ended, the mixture was stirred at room temperature for 30 minutes and was then concentrated by distilling off the solvent in vacuo. 48.5 g (quantitative conversion) of crude 1-bromo-4-(4-chlorophenoxy)-3,3-dimethyl-butan-2-one were obtained as an oil. ##STR817##
