应用 Convenient form of anhydrous HF, stable up to 50°C. Has been used for the preparation of β-fluoroamines from amino alcohols and for the fluorination of acetylenes.
Used together with hypervalent iodine(III) reagents for ipso-fluorination of para-substituted phenols providing cyclohexadienones. Employed for geminal fluorination of 2,2-diaryl-1,3-dithiolane?s.

Reactant for preparation of:
Epimers of shikimic acid with the features of fucosylated glycans via zinc-mediated reductive ring opening followed by a Barbier reaction
Vaccinia H1-related (VHR) phosphatase inhibitor with a nonacidic phosphate-mimicking core structure
Candidates for nucleic acid drugs
ω-substituted gem-difluoroalkanes by oxidative desulfurization-difluorin?ation

Reagent for:
Halofluorination reactions
