Proton sponge hydrofluoride as a soluble fluoride ion source
Abstract
Proton Sponge (PS) hydrofluoride has been prepared and is totally soluble in acetonitrile; this system was used to generate carbanions from hexafluoropropene and to form carbon–fluorine bonds by reaction with 2,4,6-trichloropyrimidine and by reaction with benzoyl chloride (Proton Sponge hydrochloride is insoluble in acetonitrile).
