(TEMPO)-mediated hydroxyfluoroalkylation of arylamines with polyfluorinated alcohols via a radical-triggered C(sp2)–H/C(sp3)–H dehydrogenative cross-coupling process was developed. This transformation features simple operation, high atom economy, broad substrate compatibility, and excellent regioselectivity, leading to a series of hydroxyfluoroalkylated arylamine derivatives. Importantly, these synthetic

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
