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

Participants

Reaction Steps

36 g (0.159 mole) of 1-(4-chlorophenoxy)-2,2-dimethyl-butan-3-one (Example 2) were dissolved in 300 ml of chloroform, and 25.5 g (0.159 mole) of bromine were added dropwise at 20° C. in a manner such that continuous decolorization occurred. After the addition, 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. ##STR41##
