    Description / Table of Contents: Formation of Three-coordinated Sulfur (VI)-Nitrogen Compounds from NSF3From NSF3 and LiN(SiR3)CR3 the three-coordinated sulfur(VI)-nitrogen compounds S(=NSiR3) (=NCR3)2 (8) and S(=NCR3)3 (9) are formed. With less bulky amines only polymerisation products are observed. The mechanism for the formation of 8 and 9 is discussed and some reactions of 8 and 9 are reported.

    Notes: The crystal structures of two pentavalent silicon anions are discussed. The structure of [SiMe3F2]- 1 shows a trigonal bipyramidal structure with the fluorines in apical positions. The Si—F bond distances are the longest known of this type. The crystal structure of fluorosilicate 2 (1,1-diphenyl-1-fluoro-3,3-bis[trifluoromethyl]-1,3-dihydro-2,1-benzoxasilole[ion 1-]) is distorted toward a rectangular structure along the Berry pseudorotation coordinate. The lone Si—F bond distance in 2 is much shorter than that in 1. The ab initio calculations on a variety of pentavalent fluorinated silicon anions are reported, and good agreement with the experimental data are found. Fluoride affinities for the fluorosilanes are reported and are in reasonable agreement with the experimental values where known. The fluoride affinity of the tetra-coordinated species is related to the length of the Si—F bond in the pentavalent anion.

    Description / Table of Contents: On Reactions of cyclo-Thiazylhalides with LEWIS AcidsS3N3Cl3 and S3N3F3 react with LEWIS acids as SbCl5 or SbF5, AsF5 and BF3 to give the ionic compounds S3N3Cl2+SbCl6- and S3N3F2+MF6-(BF4-), respectively, as it is shown by spectroscopic investigations and by comparison with the adducts S4N4 · AsF5 and S4N4 · SbCl5. In a dry atmosphere the extremely moisture sensitive salts are stable at room temperature, on heating the (NS)3 ring is cleaved; S3N3F2+AsF6- e. g. decomposes at 85°C to give NS+AsF6- and NSF. The (NSF)4 ring is even more unstable, from the reaction with excessive AsF5 in liquid SO2 a mixture of NS+AsF6- and S3N3F2+AsF6- is isolated.
    Notes: S3N3Cl3 und S3N3F3 reagieren mit LEWIS-Säuren wie SbCl5 bzw. SbF5, AsF5 und BF3 zu den ionischen Verbindungen S3N3Cl2+SbCl6- bzw. S3N3F2+MF6-(BF4-), wie aus spektroskopischen Untersuchungen und durch Vergleich mit den Addukten S4N4 · AsF5 und S4N4 · SbCl5 hervorgeht. Die stark hydrolyseempfindlichen Salze sind bei Raumtemperatur in trockenen Glasgefäßen stabil, beim Erhitzen jedoch wird der (NS)3-Ring gespalten; S3N3F2+AsF6- z. B. zerfällt bei 85°C in NS+AsF6- und NSF. Der (NSF)4-Ring ist noch wesentlich instabiler, aus der Umsetzung mit überschüssigem AsF5 in flüssigem SO2 wird ein Gemisch aus NS+AsF6- und S3N3F2+AsF6- isoliert.

    Description / Table of Contents: Electrochemical Syntheses. XXIII. Electrochemical and EPR-Spectroscopic Investigation of the Redox Behaviour of (SN)+ and [S3N3]-The eventual syntheses of SN. and (S3N3). by electrochemical reduction or oxidation, respectively, starting from (SN)+[SbF6]- and (PPN)+[S3N3]- were checked by e.p.r. spectroscopy. Only the reduction of (SN)[SbF6] yielded detectable paramagnetic species: the long-known (S3N2)+. and a radical, the e.p.r. signal of which is a quintet of triplets. This signal is not obtained by electro-chemical oxidation of CF3CO—N=(S3N2) or FSO2—N=(S3N2).
    Notes: Die eventuellen Synthesen von SN. und (S3N3). durch elektrochemische Reduktion bzw. Oxydation ausgehend von (SN)+[SbF6]- und (PPN)+[S3N3]- wurden mittels EPR-Spektroskopie überprüft. Nur die Reduktion des (SN)[SbF6] ergab nachweisbare paramagnetische Spezies: das lange bekannte (S3N2)+. und ein Radikal, dessen EPR-Signal ein Quintett von Tripletts darstellt. Dieses Signal wird durch elektrochemische Oxydation von CF3CO—N=(S3N2) oder FSO2—N=(S3N2) nicht erhalten.
