摘要:
AbstractBy 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.
