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: Das Pentabrom(1+)- Kation, Br5+. Berechnungen mit der Dichtefunktional-Methode und SchwingungsspektrenFür das Br5+-Kation werden mit der Dichtefunktional-Methode Geometrie, Schwingungsspektren und Landungsverteilung berechnet. Das freie Ion hat in der gauche-Konfiguration die niedrigste Energie. Die drei mittleren Br-Atome bilden danach einen Winkel von 168,6° und der Diederwinkel der beiden terminalen Br-Atome beträgt 82°. Diese Konfiguration steht damit im Gegensatz zu der planaren trans-Konfiguration mit C2h-Symmetrie, die für Br5+ im Br5+ MF6- (M = As, Sb) durch Röntgenbeugung gefunden wurden. Die geringe Energiedifferenz von 1,2 kcal mol-1 zwischen der gauche- und trans-Konfiguration, verbunden mit Kristallpackungseffekten, könnten für die trans-Konfiguration von Br5+ im festen Br5+MF6- verantwortlich sein.Um den wahrscheinlichsten der bereits publizierten sich stark unterscheidenden Frequenzsätze, zu bestimmen, wurden die berechneten Schwingungsspektren herangezogen.Im Gegensatz zu früheren STO-3G-Rechnungen für Cl5+, können mit diesen LDF-Rechnungen für Br5+ und Cl5+ Ladungsverteilungen wiedergegeben werden, die mit einem früher vorgeschlagenen einfachen „valencebond-model“ für Pentahalogen(1+)-Kationen übereinstimmen.
    Notes: The geometry, vibrational spectra and charge distribution of Br5+ were calculated by the use of the local density functional (LDF) method. The results show that for free Br5+ the lowest energy configuration is a skew structure with the three central Br atoms forming an angle of 168.6° und the two terminal Br atoms exhibiting a dihedral angle of 82°. This skew configuration is in contrast to the planar trans configuration of C2h symmetry found for Br5+ in solid Br5+MF6- (M = As, Sb). The small energy difference of 1.2 kcal mol-1 between the skew and the trans configurations, combined with crystal packing effects, can account for the planar trans configuration of Br5+ in solid Br5+MF6-. The computed vibrational spectra were used to select the most likely set from three sets of previously published and widely diverging spectra. Contrary to previous STO-3G calculations for Cl5+, the present LDF calculations for Br5+ and Cl5+ result in charge distributions which agree with a previously proposed simple valence bond model for pentahalogen(1+) cations.
