, p. 349 - 354 (2007/10/02)
The dinuclear titanocene complexes Cp4Ti2S6, Cp4Ti2S4 and Cp4Ti2Se4 have been reacted with SCl2, S2Cl2, and Se2Cl2, respectively.The reaction products are rings of type Sn (n=6...20) and six-, seven- and eight-membered rings of type SexSy, respectively, which have been characterized by HPLC, Raman and Se-NMR spectroscopy, as well as X-ray diffraction on single crystals.
CONVENIENT PREPARATION OF CYCLO-EICOSASULPHUR (S20) FROM BIS(η-CYCLOPENTADIENYL)(PENTASULPHIDO)TITANIUM(IV)
Steudel, Ralf,Strauss, Reinhard
, p. 1775 - 1778 (2007/10/02)
High-pressure liquid chromatographic analysis of stoicheiometric mixtures of (cp=η-cyclopentadienyl) and SO2Cl2 in CS2 solution has revealed the presence of S10, S15, S20, and S25 in order of decreasing concentration.The compound S20 has been isolated in 8percent yield and a reaction mechanism explaining its formation is proposed.An improved synthesis (88percent yield) of from is also reported.
