  Oxidation and Reduction Reactions of cis-9,10,11-Trithiabicyclo[6.3.0]undecane Synthesized by Reaction of cis-Cyclooctene with S₈O

  摘要：

  cis-Cyclooctene reacted with S8O in refluxing carbon disulfide to give cis-9,10,11-trithiabicyclo[6.3.0]undecane (1,2,3-trithiolane). Oxidation of the 1,2,3-trithiolane with m-chloroperbenzoic acid (MCPBA) or dimethyldioxirane (DMD) yielded the corresponding 1-exo-oxide, 1-endo-oxide, 2-endo-oxide, 2-exo-oxide, 1-endo,3-exo-dioxide, 1-exo,3-exo-dioxide, 1,1,3-exo-trioxide, and 1,1,3,3-tetraoxide, depending on the amount of the oxidants. Formation of another 1,3-dioxide assignable to the 1-endo,3-endo-dioxide was observed in the oxidation of the 1-endo-oxide with MCPBA. Oxidation of the 2-exo-oxide with DMD gave the 1,1,3,3-tetraoxide in low yield. Reduction of the 1,2,3-trithiolane and its trans isomer with LiAlH4 gave cis- and trans-cyclooctane-1,2-dithiol, respectively, in high yields. Oxidation of the sodium salt of the cis-1,2-dithiol with MCPBA provided the corresponding 1,2,5,6-tetrathiocane in low yield as the only identifiable product.

• Reversible isomerization of cyclo-octasulphur monoxide; preparation and X-ray crystal structure of S₈O·SbCl₅
  作者：Ralf Steudel、Torsten Sandow、Jürgen Steidel

  DOI：10.1039/c39800000180

  日期：——

  The reaction of S8O and SbCl5 in CS2 gave S8O·SbCl5(71% yield) which was shown by X-ray crystallography to contain S8O in an isomeric conformation compared with pure S8O which can be recovered from the adduct in its usual conformation by recrystallization from acetone or carbon disulphide.

  S8O 和 SbCl5 在 CS2 中反应生成了 S8O-SbCl5（产率为 71%），X 射线晶体学显示，与纯 S8O 相比，S8O 以异构体的构象存在。

  Abstract The infrared spectrum (200–4000 cm−1) and the laser Raman spectrum (10–1400 cm−1) of S8O are reported. The observed bands are compared with those of S8 and SOCl2 and a tentative assignment is given in accordance with the molecular symmetry C8.

  AbstractThe platinum S2O complex [(Ph3P)2Pt(S2O)] (10) was obtained by S2O transfer reactions from tetrathiolane 2‐oxide (8), tetrathiolane 2,3‐dioxide (5), and pentathiane 3‐oxide (6) to [(C2H4)Pt(PPh3)2] (4). The S2O complex 10 further reacts with 4 to give a novel binuclear platinum complex 16, which is found to be a source of several platinum SnOm complexes. (© Wiley‐VCH Verlag GmbH & Co.
