Halogenation of 1-trifluoromethyl enamines: A new and efficient synthesis of α-bromo- and α-iodo-trifluoromethyl ketones
摘要:
Treatment of the 1-trifluoromethyl enamines 1a-d with bromine or iodine results in the formation of the corresponding iminium salts. Treatment of any of these salts with methanol results in the formation of the corresponding alpha-halo-trifluoromethyl ketones.
