    Description / Table of Contents: Reactions of NN-Dihaloperfluoroalkaneamines with Sulfur and Sulfur DerivativesReactions of NN-Dihaloperfluoroalkaneamines RfNX2 (Rf = CF3, C2F5; X = Cl, Br) with S8, S4N4 and A = SX2 (A = RfN, O) are described. The products isolated are: Sulfurdihalideimides RfNSX2 (Rf = CF3, C2F5; X = Cl, Br), Sulfurdiimides RfNSNRf and Bis(sulfurdiimido)sulfides (RfNSN)2S(Rf = CF3, C2F5). Thionylimides RfNSO were not obtained in preparative quantities.
    Notes: Umsetzungen der NN-Dihalogenperfluoralkanamine RfNX2 (Rf = CF3, C2F5; X = Cl, Br) mit S8, S4N4 und A = SX2 (A = RfN, O) werden beschrieben. Dabei lassen sich als Produkte isolieren: Schwefeldihalogenidimide RfNSX2 (Rf = CF3, C2F5, X = Cl, Br), Schwefeldiimide RfNSNRf und Bis(schwefeldiimido)sulfide (RfNSN)2S (Rf = CF3, C2F5). Thionylimide RfNSO sind auf diesem Wege nicht in präparativem Maßstab zugänglich.

    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.

    Description / Table of Contents: Reaction of Thiazylfluoride with Multifunctional Nitrogen DerivativesFrom the reaction of NSF 1 with LiN(SiMe3)R′ (R′ = CMe3, SiMe3), linear [e. g. (Me3C—N=S=N—)2S (11), Me3C—N=S=N—CMe3 (14), Me3Si—N=S=N—SiMe3 (17), (Me3Si)2N—S—N=S=N—SiMe3 (19)] and cyclic thiazenes (S4N5F (22)) are isolated, (S3N4)n (23) is obtained in high yield from 1 and 17 (in the ratio 2:1). Possible structures for 23 are discussed; the reaction of 23 with AsF5 gives S4N4 · AsF5 (24) in a hitherto unknown modification. Possible reactions of the terminal SN groups are discussed and the structures of 11 and 24 are reported.
    Notes: Aus der Umsetzung von NSF 1 mit LiN(SiMe3)R′ (R′ = CMe3, SiMe3) werden lineare [z. B. (Me3C—N=S=N—)2S (11), Me3CNSNCMe3 (14), Me3SiNSNSiMe3 (17), (Me3Si)2N—S—N=S=N—SiMe3 (19)] und cyclische Thiazene (S4N5F (22)) isoliert, die Umsetzung von 1 mit 17 im Molverhältnis 2:1 liefert (S3N4)n (23) in hohen Ausbeuten. Strukturvorschläge für 23 werden diskutiert; die Umsetzung von 23 mit AsF5 liefert S4N4 · AsF5 (24) in einer bisher nicht bekannten Modifikation. Reaktionsmöglichkeiten der terminalen SN-Gruppe werden diskutiert und die Strukturuntersuchungen an 11 und 24 mitgeteilt.
