The halides (C6H5)2SiCl2, (C6H5)2GeBr2, and (C6H5)2SnCl2, react with Li2S and (eta-5-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 H-1 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.
