AbstractBei Umsetzung von "Ihiazylfluorid (I) mit LiN(SiMe3)R′ (R′ : C Me; (II); R′: SiMe3 (VI)) entstehen die linearen und cyclischen Thiazene (III), (IV), (VII), (VIII) bzw. (IX), die isoliert oder nur spektroskopisch nachgewiesen werden.

Nucleophilic substitutions of thiazyl fluoride (NSF) should afford access to thiazyl derivatives RSN. On reaction of NSF with LiOCMe3, the primary product “LiNS(F)OCMe3” could be trapped for the first time as the double cluster 1 and subsequently characterized. A molar ratio of NSF: nucleophile of 1:1 is essential for the formation of 1. equation image

AbstractDie in flüssigem SO2 durch F‐‐Addition (A) dargestellte Titelverbindung (I) wird durch Einengen der SO2‐Lösung in Form farbloser Einkristalle abgeschieden (rasche Dunkelfärbung durch Hydrolyse bzw. Zersetzung).

Nucleophile Substitutionen an Thiazylfluorid (NSF) sollten den Zugang zu Thiazylderivaten R—SN eröffnen. Bei der Reaktion mit LiOCMe3 ließ sich nun erstmals das Primärprodukt „LiNS(F)OCMe3”︁ als Doppelcluster 1 abfangen und durch Röntgen‐Strukturanalyse charakterisieren. Wesentlich für die Entstehung von 1 ist das Molverhältnis NSF : Nucleophil < 1 : 1.magnified image

The preparation of S4N5F by fluoride ion addition to the S4N5 +-cation in liquid SO2 is described. The structure of the fluoride was determined from single crystal data. The mechanism for the formation of S4N5F and the stability of possible isomers is discussed on the basis of MNDO/1 calculations

Abstract N2S3Cl+ SbCl6- was prepared by chlorination of N4S4 · SbCls5 with elemental chlorine. The crystals are monoclinic, P21/c, with a = 1492.4(4), b = 1233.6(2), c = 1437.5(4) pm, β = 91.40(2)°, and R = 0.059 for 3663 observed reflections. There are two independent cations and anions in the asymmetric symmetric unit. The appreciable interionic interaction results in a high density of ρ = 2.642 g · cm -3 (calcd).

The reaction of 1,1-diphenylhydrazine with S2Cl2 in the presence of triethylamine leads to 1,1-diphenylthionitrosamine. The chromium pentacarbonyl derivative was isolated and characterised by X-ray structure determination; [Cr(SNNPh2)(CO)5](2) crystallises in the space group P21/c with a= 786.5(1), b= 2 236.5(2), c= 1 054.6(1) pm, β= 89.44(8)°, and Z= 4; [Cr(SNNMe2)(CO)5](3) also crystallises in P21/c, with a= 1 042.2(3), b= 1 250.7(4), c= 954.6(3) pm, β= 110.21(3)°, and Z= 4. The structures were refined to R= 0.079 for 1 573 diffractometer data with F > 3σ(F), and R= 0.049 for 2 388 data with F > 3σ(F) respectively. The structures are similar, with CrSNNC2 planes approximately eclipsed to the carbonyls. One of the phenyl groups in (2) can take part in π interaction with the nitrogen atoms, which is associated with longer N–N and shorter S–N and Cr–S bonds in (2) than in (3).
