    Description / Table of Contents: Die Reaktion von XeF+SbF6- mit Sulfuranen; Präparation von CF3S(O)F2+SbF6- und (CF3)2SOXeF+SbF6-CF3S(O)F, (CF3)2SO, CF3SF3, (CF3)2SF2, und SF4 reagieren in unterschiedlicher Weise mit XeF+MF6- (M=As, Sb). Eine oxidative Fluorierung wird beobachtet beim CF3S(O)F unter Bildung des Persulfoniumsalzes CF3S(O)F2+SbF6-, während mit (CF3)2SO ein einfaches Xenon-enthaltendes Additionsprodukt (CF3)2SOXeF+SbF6- isoliert werden kann. Im Gegensatz dazu führt der Lewis-saure Charakter des XeF+ -Kations gegenüber (CF3)nSF4-n (n = 0 - 2) zu den entsprechenden Fluorsulfoniumsalzen (CF3)nSF3-n +MF6- (M=As. Sb) und XeF2.
    Notes: CF3S(O)F, (CF3)2SO, CF3SF3, (CF3)2SF2, and SF4 react in different manner with XeF+MF6- (M=As, Sb). An oxidative fluorination is observed by CF3S(O)F forming the persulfonium salt CF3S(O)F2+SbF6-, whereas by (CF3)2SO a simple addition product containing xenon can be isolated in form of the sulfonium salt (CF3)2SOXeF+SbF6-. On the contrary, the Lewis-acidic character of the XeF+-cation predominates against (CF3)nSF4-n (n = 0 - 2) leading to the corresponding fluorosulfonium salts (CF3)nSF3-n +MF6- (M=As, Sb) and XeF2.
