実験手順

210 g (0.81 mol) of 4-chloro-1-(4-chlorophenoxy)-3,3-dimethyl-butan-2-one were dissolved in 1,000 ml of carbon tetrachloride. 41 ml (0.01 mol) of bromine were added dropwise at room temperature at a rate such that it was continuously consumed. The mixture was then stirred at room temperature for 30 minutes. After distilling off the solvent in vacuo, 268.3 g (98% of theory) of crude 1-bromo-4-chloro-1-(4-chlorophenoxy)-3,3-dimethyl-butan-2-one were obtained and were further reacted directly. ##STR13##
