Electron spin resonance spectra observed in dilute solutions of the hexafluoroarsenate salts of selenothiadiazolylium cations in I --polar solvents are ascribed to the parent cation radicals SeNSeSeN', SNSeSeN', ~N S~S A ' , and SNSSN+ . The g-and nitrogen hyperfine tensors for the three selenium-containing species are entirely in line with the planar w-radical description deduced in earlier studies of trithiadiazolylium. Substantial increases in the g-shifts on substitution of sulphur by selenium result in broadening of the solution spectra and concomitant loss of nitrogen hyperfine structure. From measurements made in solid SOz, the following principal tensor components were deduced for the new, Se-containing radicals: -N+: g = (1.9930, 2.0108, 2.1379), aN(2) = (7.4, -0, -0) gauss, ase(2) = (180, 70, 43) gauss; -N+: g = (1.9941, 2.0108, 2.1355), aN(2) = (6.9, -0, =0) gauss, ase (2) [Traduit par la revue]

“…ClSN --* MCl,, especially since the reaction of [SN][SbCI,] or [sN][AsF,] 7*8 with elemental sulphur has been found to yield S2N+ salts; in the case of [SN][AsF,], the reaction is quantitative. 8 We were interested in extending this synthetic principle to obtain a more convenient preparation of an S,N+ salt. It has been shown that S2N+ has an extensive and diverse chemistry9g'0 and is of increasing use as a 'building block' in synthesis of sulphur-nitrogen compounds.…”

Reaction of (NSCI), with SbCI, in thionyl chloride or methylene chloride, in molar ratio 1 : 3, followed by the addition of three equivalents of elemental sulphur produces [S,N] [SbCI,], [S,N,CI] [SbCl,], and [NS,CI,] [SbCl,]; the adduct S,N,eSbCI, was also produced in methylene chloride. The products can be separated by solvent extraction; the overall yield of [S,N] [SbCI,] is 35%. A similar reaction in methylene chloride using FeCI, instead of SbCI, produced [SGN,] [ FeCI412-Reactions of Lewis acids with (NSCl), have been extensively studied. ' The products isolated depend on reaction conditions and molar ratios of reactants. The intermediate precipitates formed in these reactions, although not separately characterised, have been used as in situ sources of the reactive SN+ cation, e.g. for the synthesis of SSN5+ and NS2C12+ salts: equations (1)
