10. Perfluoroalkylation of bis(tetrafluoro-4-pyridyl) disulfide

New 4-pentafluorosulfanyl and 4-perfluoroalkylthio derivatives of 1-chloro-2-nitro- and 1-chloro-2,6-dinitrobenzenes

“…Recently, we have also developed a method for perfluoroalkylation of heterocyclic thiols and disulfides by means of thermolytic reactions with xenon (II) bis(perfluoroalkylcarboxylates) [23]. By using disulfides 1a,b, the method was successfully extended to this class of aromatic compounds.…”

Aromatic and heterocyclic perfluoroalkyl sulfides. Methods of preparation

“…Similar reactions have been carried out with tetrafluoropyridine 4-thiol [ 224 ] and its corresponding disulfide [ 225 – 226 ] (40–50% yield). The formation of S -perfluoroalkyl derivatives with performed xenon carboxylates from nitro aromatic disulfides was also successful ( Scheme 60 ).…”
