実験手順
3-Methyl-3-trifluoromethylthio-butan-2-one was dissolved in chloroform and bromine was added dropwise at 20° C. at such a rate that decolorization occurred continuously. Addition was stopped when the color persisted, the reaction mixture was further stirred at 40° C. 1-Bromo-3-methyl-3-trifluoromethylthio-butan-2-one of boiling point 56° C./0.4 mbar was obtained in a yield of 85%. ##STR13##
