“…As expected from the reported densities at 25°C of 1.726 g cm-3 (26) for HS03F and 1.645 g cmP3 for S2O6F2 (31), the latter is the principle constituent of the upper layer. The volume of this upper layer increases steadily with increasing KS03F concentration or decreasing temperature and contains at 25OC the bulk of the S206F2 for a 3.1 M KS03F solutions.…”

Solutions of bis(fluorosulfuryl)peroxides, S2O6F2, in fluorosulfuric acid, HSO3F, are synthetically very useful. The nature of the solvent (HSO3F)–solute (S2O6F2 or SO3F•) interaction is probed by Raman, 1H and 19F NMR, and ESR spectroscopy, the latter focussing on the radical SO3F• formed by the dissociation of S2O6F2. Both S2O6F2 and SO3F• behave as very weak bases in HSO3F. Proton transfer between solvent and solute and SO3F exchanges are suggested on the basis of NMR and ESR measurements. The symmetry and electronic structure of the SO3F• radical are altered in HSO3F solution. A giso value of 1.97267 is obtained. The radical appears to be formed on dissolution of S2O6F2 at room temperature and persists down to 183 K. The solvent–solute interaction depends on the acid strength of the protonic solvent and addition of the base KSO3F to HSO3F leads to a loss of solubility and the separation of S2O6F2 as a second phase. Keywords: solution study in HSO3F of weak bases, Raman spectrum, ESR study in HSO3F.

“…Peroxydisulfuryl difluoride, S206F2, has been known for some time (l,2) and has proven to be an extremely versatile reagent in synthetic inorganic chemistry (3)(4)(5). Even though some relevant structural details, such as the infrared spectrum in the NaCl region (I), the "F nuclear magnetic resonance (n.m.r.)…”

“…E = olefin substrate SF5 compounds exhibit a wide range of useful and interesting properties • . For example, SF6 (14), CF 3 SF5 (14), SF 5 CF=CF2 (1.5), and SF5-oxetanes (16) possess unusual dielectric strength while S2F10 (14), and SF5CF=CF2 (17) are biologically active. :rnaddition, SF6 (14), SF5Rf (18), SF5-oxetanes (16) The purpose of this work was to further study the thermal addition reaction of -SF5Br with fluoroolefins and in particular to determine the nature of the groups attached to double bonds that favored the addition of SF5Br.…”
