Hexafluoropropylene dimer (HFPD) was directly employed to synthesize perfluoro alkyl/alkenyl aryl sulfides. A variety of thiophenol substrates were conveniently chlorinated by N-chlorosuccinimide (NCS); afterwards, C6 perfluoroalkyl was introduced in the presence of cesium fluoride (Path A). Moreover, the C6 perfluoroalkenyl was directly constructed by inorganic base-catalyzed nucleophilic substitution
Fluorinated Tertiary Thio- and Selenoethers from the Reaction of Sulfenyl or Selenenyl Chloride with Perfluoropropene Dimers in the Presence of Alkali Fluoride
Perfluoro(1,1-dimethylbutanide) anion generated from hexafluoropropene dimers and alkali fluorides in dry N,N-dimethylformamide, reacts with arenesulfenyl or areneselenenyl chloride to give the corresponding aryl perfluoro(1,1-dimethylbutyl) sulfides or selenides in low to good yields.
