A powerful, new reagent, an amidinate salt of hexafluoroacetone hydrate, is an air-stable salt that can be used for the preparation of fluorinated organic molecules. Nucleophilic trifluoromethylation reactions are demonstrated following the base-promoted release of trifluoroacetate. This reagent is soluble in many polar organic solvents and produces fluoroform, following the release of trifluoroacetate

The present invention relates to compositions, for example, the DBU/Hexafluoroacetone hydrate salt, and processes of preparing and using the same for the modification of chemical compounds via the release of trifluoroacetate. The DBU/Hexafluoroacetone hydrate salt can perform trifluoromethylation reactions on chemical compounds, such as carbonyl group-containing compounds.
