    Description / Table of Contents: Preparation of Cyanhalogenomethyl and Dicyanhalogensulfonium Salts CH3(CN)SHal+MF6- and (CN)2SHal+MF6- (Hal = F, Cl, Br, I; M = As, Sb) and Methylthionitrilium and (μ-Thio)bisnitriliumhexafluoro Metallates CH3SCNX+MF6- and S(CNH)22+ (MF6-)2 (X = H, D)Oxidative halogenation of CH3SCN and S(CN)2 with XeF+MF6-, Cl2/MF5/SO2, Br2/MF5/SO2 and I3+MF6- leads to S-coordinated cations. The complete spectroscopic series of the halogensulfonium salts CH3S(CN)Hal+MF6- and (CN)2SHal+MF6- (Hal = F, Cl, Br, I; M = As, Sb) as well as hexafluoroarsenate and -antimonate were recorded.However the protonation of divalent cyansulfanes in superacidic media HF/MF5 takes place at the nitrogen atom to nitrilium salts in analogy to the adduct formation with strong Lewis acids.
    Notes: Bei der oxidativen Halogenierung von CH3SCN und S(CN)2 mit XeF+MF6-, Cl2/MF5/SO2, Br2/MF5/SO2 und I3+MF6- erfolgt eine Koordination am Schwefel, und es wurden die kompletten spektroskopischen Reihen der S-Halogensulfoniumsalze CH3S(CN)Hal+MF6- und (CN)2SHal+MF6-(Hal = F, Cl, Br, I; M = As, Sb) jeweils als Hexafluoroarsenat und -antimonat hergestellt.Dagegen erfolgt die Protonierung der divalenten Cyansulfane im supersauren Milieu HF/MF5 am Stickstoff zu Nitriliumsalzen analog wie die Koordination bei der Adduktbildung mit starken Lewissäuren.

    Description / Table of Contents: On the Crystal Structures of CH3PF2H+AsF6- and CH3PF2H+SbF6- and a simple Method for Preparation of CH3PF2A simple method for preparation of CH3PF2 from CH3PCl2 is reported. The phosphonium salts CH3PF2H+MF6- are obtained by the reaction of CH3PCl2 with superacidic systems HF/MF5 (M = As, Sb). CH3PF2H+SbF6- crystallizes in the space group P1 with a = 548.4(4) pm, b = 695.5(8) pm, c = 960.2(9) pm, α = 94.68(5)°, β = 97.19(6)°, γ = 94.41(6)° and Z = 2. CH3PF2H+SbF6- crystallizes in P1 with a = 554.3(3), b = 724.2(4), c = 970.4(5), α = 94.73(4)°, β = 96.14(5)°, γ = 95.30(4)°.
    Notes: Es wird über eine einfache Darstellung von CH3PF2 aus CH3PCl2 berichtet, welches in den supersauren Systemen HF/MF5 (M = As, Sb) zu den Phosphoniumsalzen CH3PF2H+MF6- protoniert wird. CH3PF2H+AsF6- kristallisiert in der Raumgruppe P1 mit a = 548,4(4) pm, b = 695,5(8) pm, c = 960,2(9) pm, α = 94,68(5)°, β = 97,19(6)°, γ = 94,41(6)° und Z = 2, das isostrukturelle CH3PF2H+SbF6- mit a = 554,3(3), b = 724,2(4), c = 970,4(5), α = 94,73(4)°, β = 96,14(5)°, γ = 95,30(4)°.
