    Description / Table of Contents: Ein Derivat der Perthiokohlensäure H2CS4: Röntgenstrukturanalyse von Bis(triphenylmethyl)perthiocarbonat (Ph3C)2CS4Die Molekülstruktur von Ph3CSSC(S)SCPh3 · CS2 wurde durch eine Röntgenstrukturanalyse bestimmt. Die Substanz kristallisiert im triklinen Kristallsystem [a = 884,9(2) pm, b = 1 039,5(2) pm, c = 2 064,6(3) pm, α = 75,86(1)°, γ = 79,83(2)°, γ = 77,31(5)°, Z = 2, Raumgruppe P1]. Die CS3-Gruppe ist planar; die S—S-Bindung (201,4 pm) bildet mit der CS3-Ebene einen Winkel von 5,7°. Der CSSC-Torsionswinkel beträgt 96,3°. (Ph3C)2CS4 wurde durch Umsetzung von TosNSCl2 (Tos = p-MeC6H4SO2) mit Ph3CSH in CS2 in Gegenwart von Triethylamin erhalten. Der Reaktionsmechanismus wird diskutiert.
    Notes: The molecular structure of Ph3CSSC(S)SCPh3 · CS2 has been determined by X-ray structural analysis. The substance crystallizes in the triclinic crystal system [a = 884.9(2) pm, b = 1 039.5(2) pm, c = 2 064.6(3) pm, α = 75.86(1)°, β = 79.83(2)°, γ = 77.31(5)°, Z = 2, space group P1]. The CS3 group is planar; the S—S-bond (201.4 pm) forms an angle of 5.7° with the CS3 plane. The torsional angle CSSC equals 96.3°. (Ph3C)2CS4 was obtained by reaction of TosNSCl2 (Tos = p-MeC6H4SO2) with Ph3CSH in CS2 in the presence of triethylamine. The reaction mechanism is discussed.

    Notes: Treatment of Cp2Ti(CO)2 (3) with the di- and polysulfanes 1,2,4-(CH2)2S3, C4S6 (9), C,7H10S3 (11), 1,2,4,6-(CH2)3S4 (16), C6H10S6(19), and S6 affords the titanocene chelate complexes Cp2TiS3(CH2)2 (8), (Cp2Ti)2C4S6 (10), Cp2TiS3C7H10 (13), Cp2TiS2C7H10 (14), Cp2TiS4(CH2)3 (17), Cp,2TiS6C6H6H10 (20), and Cp2TiS8 (23). 14 is also obtained from Cp2TiCl2 (1) and the geminal dithiol of norbornene. The analogous reaction with the dithiol of dicyclopentadiene yields Cp2TiS2C10H12 (15). In ligand transfer reactions, 8 reacts with SCl2 to give 1,2,3,5-tetrathiane (25), 10 provides 9 on reaction with Cl2, 13 when treated with S2Cl2 affords C7H10S5 (12), 15 reacts with S2Cl2Cl2 to give C10H12S4. 17 and SCl2 yield 1,2,3,5,7-pentathiepane (18), 20 is converted to C6H10S7 (22) on reaction with SCl2, and 23 yields S10 and 1,2,-C6H4(SCl)2, respectively. With phosgene, thiophosgene, and thionyl chloride, compound 15 yields the corresponding dithiocarbonate 26, the trithiocarbonate 27 and the trisulfane 2-oxide 28. The structure of 27 was determined by X-ray crystallography.

    Description / Table of Contents: Darstellung spirocyclischer organischer Polysulfane des Typs C6H10Sn und Röntgenstrukturanalyse von C6H10S11Durch Reaktion von (C5H5)2Ti(μ-S2)2C6H10 3 mit S2Cl2 wurde 7,8,9,10,11,12-Hexathiaspiro[5,6]dodecan 4 hergestellt (Ausbeute 51%), das durch UV-, IR-, Raman-, Massen- und NMR-Spektren (1H, 13C) charakterisiert wurde. Die NMR-Spektren zeigen, daß der siebengliedrige CS6-Ring in Lösung Pseudorotation erleidet. Mit S7Cl2 reagiert der Komplex 3 zu 7,8,9,10,11,12,13,14,15,16,17-Undecathiaspiro-[5.11]heptadecan 5 (Ausbeute 23%). Die gelben, monoklinen Kristalle von 5 bestehen aus spirocyclischen C6H10S11-Molekülen, deren C6-Ring Sesselkonformation aufweist, während der CS11-Ring eine dem cyclo-Dodecaschwefel S12 entsprechende Konformation besitzt. Alle Glieder der homologen Reihe C6H10Sm (m = 5-14) wurden mittels HPLC charakterisiert.
    Notes: By reaction of (C5H5)2Ti(μ-S2)2C6H10 3 with S2Cl2 7,8,9,10,11,12-hexathiaspiro-[5.6]dodecane 4 is prepared (yield 51%) and characterized by UV, IR, Raman, mass, and NMR spectra (1H, 13C). The seven-membered CS6 ring undergoes pseudorotation in solution. With S7Cl2 the complex 3 yields 7,8,9,10,11,12,13,14,15,16,17-undecathiaspiro[5.11]heptadecane 5 (yield 23%). The yellow, monoclinic crystals of 5 consist of spirocyclic C6H10S11 molecules with the C6 ring in a chair-conformation while the CS11 ring is of the same conformation as cyclododecasulfur S12. UV, IR, Raman, mass and NMR-spectra of 5 are reported. A mixture of dichlorosulfanes SnCl2 (n = 1 -8) reacts with 3 to give the homologous series C6H10Sm which was characterized by reversed-phase HPLC for m = 5 - 14.
