"The complex [TiCl2{eta(5)-C5Me4(SiMe2H)}(2)] (3) was prepared by reacting the lithium salt of 2,3,4,5-tetramethyl-1-(dimethylsilyl)cyclopenta-2,4-diene (1) with [TiCl3(THF)(3)] followed by chlorination of the formed [TiCl{eta(5)-C5Me4(SiMe2H)}(2)] (2) with PbCl2. The reduction of 3 with excess magnesium in THF in the presence of excess bis(trimethylsilyl)ethyne (btmse) afforded the bivalent metal ansa disilylene complex with pi-coordinated btmse [Ti{eta(5)-C5Me4(SiMe2)}(2)(eta(2)-btmse)] (4). The dehydrocoupling of the SiMe2H groups was accompanied by hydrogen transfer to the free btmse. Analogous reduction of 3 with magnesium in the presence of ethene gave a mixture of titanocene [Ti{eta(5)-C5Me4(SiMe2Et)}(2)] (5) and its ethene complex [Ti{eta(5)-C5Me4(SiMe2Et)}(2)(eta(2)-C2H4)] (6). ..."@en .
