Two novel Cp2Ti(Cl)S3R'S3Tr complexes have been prepared by reaction of the six-membered metallacycles Cp 2TiS4R' (Cp = η5-C5H 5, R' = CMe2, 1,1-C6H10) with the sulfenyl chloride TrSCl (Tr = CPh3) at 20 °C. These complexes were treated with: (a) sulfenyl chlorides (RSCl or RSSCl) to obtain 11 new thiaalkanes of the type R-Sx-R'-Sy-R (R = Tr, 4-ClC 6H4, 2-C10H7; x = 3, y > 2), or (b) with SO2Cl2, SCl2 or S2Cl 2 to prepare six sulfur-rich species of the type Tr-S x-R'-Sy-R'-Sz-Tr (x, z = 3, y > 3), as well as Cp2TiCl2. The thiaalkanes decompose upon heating to give mixtures of various linear and cyclic polysulfanes R2S n and R'Sm. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.
