Pyridine hydrofluoride (also named as Olah′s reagent, PPHF) is a convenient reagent for organic fluorination reactions, e.g. employed with selectfluor for the geminal fluorination of 2,2-diaryl-1,3-dithiolanes. It is also used as reactant for the preparation of various target compounds, such as 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-difluorination, etc..
