    Description / Table of Contents: Preparation and Spectroscopic Characterization of the Persulfonium Salts (CH3)(CF3)SF3+SbF6- and (CH3)(CF3)2SF2+SbF6- and Crystal Structure of CF3SF2+SbF6- [1].The preparation of the persulfonium salts (CH3)(CF3)SF3+SbF6- and (CH3)(CF3)2SF2+SbF6- by methylation of the sulfuranes CF3SF3 and (CF3)2SF2 with CH3OSO+SbF6- in liquid SO2 is reported. The thermolabile compounds are characterized by IR, Raman, 1H, 13C, and 19F NMR spectroscopy.CF3SF2+SbF6- crystallizes in the space group C2/c with a=16.889(8) Å, b=7.261(4) Å, c=13.416(7) Å, β=91.08° with 8 formula units per unit cell at 167 K. Cations and anions are connected via short SF contacts forming a Ψ-octahedral surrounding of the central S atom which is in close analogy to the already known CF3SF2+AsF6-.
    Notes: Es wird über die Darstellung der Persulfoniumsalze (CH3)(CF3)SF3+SbF6- und (CH3)(CF3)2SF2+SbF6- durch Methylierung der Sulfurane CF3SF3 und (CF3)2SF2 mit CH3OSO+SbF6- in flüssigem SO2 berichtet. Die thermolabilen Verbindungen werden durch IR-, Raman-, 1H-, 13C- und 19F-NMR-Spektroskopie charakterisiert. CF3SF2+SbF6- kristallisiert in der Raumgruppe C2/c mit a=16,889(8) Å, b=7,261(4) Å, c=13,416(7) Å, β=91,08° und 8 Formeleinheiten pro Einheitszelle bei 167 K. Kationen und Anionen sind über kurze SF-Kontakte verbunden und bilden eine Ψ-oktaedrische Umgebung des zentralen S-Atoms. Diese Struktur stimmt gut mit der des bereits bekannten CF3SF2+AsF6- überein.

(CH3)4N+CF3ICl- and (CH3)4N+CF3IBr- are obtained via addition of CF3I with the corresponded tetramethylammonium halogenide. (CH3)4N+CF3IOCF3- is synthesized by comproportionation of (CH3)4N+CF3ICl- with CF3OCl under formation of Cl2 at -78°C. (CH3)4N+CF3IF- is formed either, through thermolysis of (CH3)4N+ CF3IOCF3- under separation of COF2, or reaction of CF3I with (CH3)4N+ OCF3-. The thermolabile compounds have been characterized by i.r., Raman, 19F-, 13C NMR spectroscopy.
    Notes: Es wird über die Darstellung einer Reihe neuer Iodate(I) des Typs CF3IX- (X = F, Cl, Br, OCF3) berichtet. (CH3)4N+CF3ICl- und (CH3)4N+CF3IBr- werden durch Additionsreaktion von CF3I an die entsprechenden Tetramethylammoniumhalogenide dargestellt. (CH3)4N+CF3IOCF3- erhält man durch Komproportionierung von (CH3)4N+CF3ICl- mit CF3OCl bei -78°C. CF3IF- entsteht sowohl, durch die Thermolyse von (CH3)4N+ CF3IOCF3- unter Abspaltung von COF2 bei -20°C, als auch durch Umsetzung von CF3I mit (CH3)4N+OCF3- bei -20°C.Die thermolabilen Verbindungen werden durch IR-, Raman-sowie Multikern-NMR-Spektroskopie charakterisiert.

    Description / Table of Contents: Photoelectron Spectra and Molecular Properties. 133. Trifluoromethyldisulfane and Derivates F3CSSX (X=CF3, F, Cl, Br)The He(I) photoelectron spectra of trifluoromethyldisulfane F3CSSH and its derivatives F3CSSX (X=CF3, F, Cl, Br) are assigned by Koopmans correlations, IEnv = -εjMNDO, with MNDO eigenvalues and by radical cation state comparison. Of special interest are the nSπ/nSπ splittings, which amount to 1.15 eV F3C—SS—F or 0.87 eV in F3—SS—Cl, and the dependance of which on the dihedral angle ω(XS—SX), on the SS bond length and on the acceptor effect of the F3C substituents is discussed.
    Notes: Die He(I)-Photoelektronen-Spektren von Trifluormethyldisulfan F3CSSH und seinen Derivaten F3CSSX (X = CF3, F, Cl, Br) werden durch Koopmans-Korrelationen, IEnv = -εjMNDO, mit MNDO-Eigenwerten und durch Radikalkationzustands-Vergleiche zugeordnet. Von besonderem Interesse sind die nSπ/nSπ- Aufspaltungen, die in F3C—SS—F 1,15 eV oder in F3C—SS—Cl 0,87 eV betragen und die in Abhängigkeit vom Diederwinkel ω(XS—SX), der SS-Bindungslänge und dem Akzeptor-Effekt der F3C-Substituenten diskutiert werden.
