Application

Ethyl trifluoroacetate can be used:

• To synthesize cyclopentenones or furans containing trifluoromethyl group from aromatic ynones.
• In the selective trifluoroacetylation of anilines catalyzed by 4-dimethylaminopyridine.
• As a starting material in the two-step electrosynthesis of trifluoroacetyltrimethylsilane (CF₃COSiMe₃).
• In the preparation of trifluoromethyl ketones via trifluoroacetic ester/ketone metathesis with alkyl aryl ketones.
• To synthesize o-fluorinated trifluoro acetophenones from substituted fluorobenzene.
