    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.

    Description / Table of Contents: Synthesis of the Dichloromethyleneiminium Salts Cl2C=NClH+MF6- and Cl2C=NClCH3+ MF6- (M = As, Sb) and Crystal Structure of Dichloromethyleneiminium-hyxachloroantimonate Cl2C=NH2+SbCl6-The N-chloro-dichloromethyleneiminium salts Cl2C=NCIH+MF6- (M = As, Sb) are prepared by protonationof trichloromethyleneimine in the superacide system HF/MF5 at 195 K. The synthesis of the N-chloro-N-methyl-dichloromethyleneiminium salts Cl2C=NClCH3+MF6- (M = As, Sb) is proceeded by methylation of perchloromethylenimine by CH3OSO+MF6- in SO2 also at low temperature. All salts are characterized by vibrational and NMR spectra. The dichloromethyleneiminiumhexachloroantimonate crystallizes in the space group P21/c with a = 971.3(4)pm, b = 1134.0(4)pm, c = 2154.2(7)pm β = 102.04(3)° and Z = 8.
    Notes: Die N-Chlor-dichlormethyleniminium-Salze Cl2C=NClH+MF6- (M = As, Sb) werden aus Trichlormethylenimin durch Protonierung mit dem supersauren System HF/MF5 bei 195 K dargestellt. Die Synthese der N-Chlor-N-methyl-dichlormethylen-iminium-Salze Cl2C=NClCH3+MF6- (M = As, Sb) erfolgt durch Methylierung von Perchlormethylenimin mit CH3OSO+MF6- in SO2 ebenfalls bei tiefer Temperatur. Alle Salze werden schwingungs- und NMR-spektroskopisch charakterisiert. Dichlormethyleniminiumhexachloroantimonat kristallisiert monoklin in der Raumgruppe P21/c mit a = 971,3(4)pm, b = 1134,0(4)pm, c = 2154,2(7) pm, β = 102,04(3)° und Z = 8.
