All substrates reacted exothermically, and sometimes explosively, between 80-298 K. The presence of the byproducts obtained may be rationalized by the thermal decomposition of some of the FOSO2F, which proceeds along two pathways, i.e. FOSO2F {\textendash}> 1/2O2 + SO2F2 and FOSO2F {\textendash}> 1/2F2 + 1/2S2O6F2, during the extremely exothermic reactions via radical intermediates. The fluorine formed gives rise to fully fluorinated products, and the SO3F. radicals, initially formed, either dimerize to give S2O6F2 or decompose to O2 and S2O5F2. Element fluoride-fluorosulfates, when formed at all, were obtained in low yields only when SO2F2 or SO2FCl were used as suitable moderators. The complete vibrational spectra of EF5OSO2F (E = S, Se or Te) have been studied and assigned. The reactions of I2, Br2 and AsF3 with FOSO2F yielded viscous liquids of the approximate, non-stoichiometric composition EFn(SO5F)5-n (E = As or I) and EFn(SO3F)3-n (E = Br), with n = non-integral number. All compounds were characterized by their vibrational and F-19 NMR spectra, and in the case of SeF5OSO2F by Se-77 NMR methods.}, keywords = {DERIVATIVES, GOLD(III) FLUOROSULFATE, halogen, ION, SPECTRA, TRIS(FLUOROSULFATE)}, isbn = {0022-1139}, url = {://A1992KF32100004}, author = {Willner, H. and Mistry, F. and Aubke, F.} }
