Abstract

PURPOSE:To obtain a compound useful as a trifluoromethylating agent in a short time safely and in high yield, by reacting trifluoroacetic anhydride with hydrogen peroxide in the presence of sodium carbonate and/or potassium carbonate. CONSTITUTION:Trifluoroacetic anhydride is reacted with hydrogen peroxide in the presence of sodium carbonate and/or potassium carbonate in the molar ratio of 1:0.05-2.0:0.05-3.0 at -20-0 deg.C for 20-60minutes to give the aimed substance. This compound is useful as a trifluoromethylating agent of trifluoromethylating compounds suitable as synthetic intermediates for polymerization initiator, drug, agricultural chemical, etc. Since a specific production device is not required in production, this method is also industrially effective.
