air-stable peptide coupling reagent TFFH (tetramethylfluoroformamidinium hexafluorophosphate) was found to activate a variety of alcohols towards deoxofluorination. These conditions are compatible with carbonyl functional groups thus offering interesting possibilities for the application to sensitive molecules. deoxofluorination - fluoroformamidinium -fluoride- TFFH -fluorination

Deoxyfluorination is a primary method for the formation of C-F bonds. Bespoke reagents are commonly used because of issues associated with the low reactivity of metal fluorides. Reported here is the development of a simple strategy for deoxyfluorination, using first-row transition-metal fluorides, and it overcomes these limitations. Using CuF2 as an exemplar, activation of an O-alkylisourea adduct

Monofluorinated compounds are easily prepared in good yields by treating phenyl sulfides with methyl fluorosulfonate and cesium fluoride in refluxing dichloromethane, successively. This reaction proceeds under so mild conditions as not to affect the coexisting bromine substituent.
