developed to access novel CF3(OCF3)CH‐containing compounds. Deprotonation of CF3(OCF3)CH‐substitutedarenes afforded synthetically useful CF3O‐substituted gem ‐difluoroalkenes. Furthermore, evaluation of the lipophilicities (log P ) indicated that CH(OCF3)CF3 is more lipophilic than the common fluorinated motifs such as CF3, OCF3, and SCF3, thus rendering the CH(OCF3)CF3 motif appealing in drug discovery

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.
