Description

General description

Potassium trifluoroacetate is used as a versatile chemical reagent in various organic reactions. It can be employed as a source of trifluoroacetyl anion (CF₃CO^2-) in reactions involving nucleophilic substitution and acylation reactions.

Application

Potassium trifluoroacetate can be used as a reagent in trifluoromethylation reactions. It is used to synthesize trifluoromethyl thioethers via iron(II) chloride-catalyzed decarboxylation as well as a subsequent trifluoromethylation of organothiocyanates.
