Preparation and characterization of chlorodifluorosulfur(IV) hexafluoroarsenate

The stable salt [SF2Cl]+[AsF6]- was prepared and isolated in good yield from the reaction of trans-CF3SF4Cl and AsF5. The identity and ionic nature of this salt were established by its elemental analysis and by 19F NMR, IR, and mass spectral studies. Redistribution of the halogen atoms in the cation of [SF2Cl]+[AsF6]- to form [SF3]+[AsF6]- and [SCl3]+[AsF6]- in liquid SO2 occurred at ambient temperature. In the presence of NaF or NaCl, [SF2Cl]+ was converted to [SF3Cl] or [SF2Cl2], respectively, at low temperature, where redistribution occurred to form SF4 and [SCl4].
