Trifluoroacetyl fluoride is an organic compound of fluorine, oxygen, and carbon with the chemical formula C2F4O.[1] The compound belongs to the group of carboxylic acid fluorides, specifically the fluoride of trifluoroacetic acid.
Trifluoroacetyl fluoride can be prepared by the reaction of trifluoroacetic anhydride and anhydrous hydrogen fluoride:[2]
- (CF3CO)2O + HF → CF3COF + CF3COOH
or by the reaction of trifluoroacetic acid and vanadium pentafluoride:[3]
- CF3COOH + VF5 → VOF3 + HF + CF3COF↑
