                                    AbstractTwo novel Cp2Ti(Cl)S3R′S3Tr complexes have been prepared by reaction of the six‐membered metallacycles Cp2TiS4R′ (Cp = η5‐C5H5, 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‐ClC6H4, 2‐C10H7; x = 3, y > 2), or (b) with SO2Cl2, SCl2 or S2Cl2 to prepare six sulfur‐rich species of the type Tr−Sx−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 R2Sn and R′Sm. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
