Sulphur compounds. CXLV. Synthesis and properties of Cp2TiS2SiR2, Cp2TiS2GeR2, and Cp'2TiS2SnR2 (Cp = η5-C5H5, Cp' = η5-C5H4CH3, and R = C6H5)

The halides (C6H5)2SiCl2, (C6H5)2GeBr2, and (C6H5)2SnCl2, react with Li2S and (η5-C5H4R)2TiCl2 (R = H, CH3) to give respectively the four-membered titanacycles Cp2TiS2Si(C6H5)2, Cp2TiS2Ge(C6H5)2, and Cp'2TiS2Sn(C6H5)2 which have been characterized by 1H NMR, mass and UV spectroscopy.The new compounds form green crystals, which react with sulphur chlorides with precipitation of (C5H4R)2TiCl2.This reaction provides a route to formerly unknown sulphur-rich heterocycles of Group 14 elements.

The silicon- and germanium-containing titanocene complexes Cp2TiS2Si(C6H5)2 and Cp2TiS2Ge(C6H5)2 (Cp = η5-C5H5) react with S2Cl2 and (CH2SCl)2, respectively, to give five- and seven-membered heterocycles which have been characterized by mass and 1H NMR spectroscopy.
