Bromine → 1-Bromo-5-chloro-1-(4-chlorophenoxy)-3,3-dimethylpentan-2-one

Participants

Reaction Steps

136 g (0.5 mol) of 1-(4-chlorophenoxy)-5-chloro-3,3-dimethyl-2-pentanone are dissolved in 1000 ml of methylene chloride. 79.9 g (1 mol) of bromine are added dropwise at room temperature such that the solution is always decolorized. The reaction mixture is then subsequently stirred at room temperature for 1 hour and is concentrated by distilling off the solvent. A quantitative yield, that is to say 177 g, of 1-bromo-1-(4-chlorophenoxy)-5-chloro-3,3-dimethyl-2-pentanone is obtained, and is further reacted directly. ##STR29##
