  Raman, mass, and 77se nmr spectra of sescl2 and its reactions with potassium iodide and titanocene pentasulphide to produce cyclic selenium sulphides

  摘要：

  Mixing of S2Cl2 and Se2Cl2 at 21-degrees-C results in the formation of SeSCl2 as shown by Se-77 NMR, mass, and Raman spectroscopy. The enthalpy of this reaction has been determined as + 13 kJ mol-1 (S2Cl2), and the equilibrium constant K(c) = 0.066 at 294 K. In addition, the formation of other Se - S - Cl molecules and of SeCl2 is observed. An Se2Cl2-S2Cl2-SeSCl2 mixture (Se:S = 1:1) reacts with titanocene pentasulphide to give mainly S7, SeS6 and 1,2-Se2S5 but small concentrations of six-, eight-, nine- and 12-membered Se - S ring molecules have also been observed. The reaction of Se2Cl2-S2Cl2 mixtures (Se: S = 1:2) with potassium iodide affords 1,2,5-Se3S5 as the major product followed by 1,2-Se2S6, 1,4-Se2S6 and 1,3-Se2S6. HPLC analysis of this reaction shows, however, that selenium sulphide ring molecules of ring sizes 6-8 are formed. Mixing of SCl2 and Se2Cl2 at 21-degrees-C results in precipitation of SeCl4 and formation of S2Cl2, which reacts with Se2Cl2 to give SeSCl2.
