BrF3–KHF2: An air-stable fluorinating reagent

•An air-stable fluorinating reagent was prepared from BrF3 and KHF2.•BrF3–KHF2 was used in the various fluorination reactions.•Desulfurizing fluorination reactions of benzylic sulfides, dithioacetals and trimethyl trithioorthocarboxylates were performed.

BrF3–KHF2, an air-stable solid prepared from BrF3 and KHF2, was used in the various fluorination reactions, including desulfurizing fluorination reactions of benzylic sulfides, ketone and aldehyde dithioacetals, (phenylthio)glycosides, and trimethyl trithioorthocarboxylates. As the results, one to three fluorine atoms were selectively introduced to the substrates.
