Resumen
The synthesis of (C5H4)(SiMeCl2)(SiMe3) is described. The reaction of a dichloromethane solution of this compound with one equivalent of titanium tetrachloride leads to the monocyclopentadienyl complex [TiCl3{η5-C5H4(SiMeCl2)}]. Treatment of this complex with the lithium amides LiN(SiMe3)2 and LiNHtBu affords [TiCl2{N(SiMe3)2}{η5-C5H4(SiMeCl2)}] and [TiCl2{η5-C5H4[SiMeCl(η-NtBu)]}], respectively. Alkylation of the trichlorotitanium derivative with 1.5 equivalents of Mg(CH2C6H5)2(THF)2 leads to the tribenzyl derivative [Ti(CH2C6H5)3{η5-C5H4(SiMeCl2)}]. Hydrolysis of the trichloro- and tribenzyl-complexes leads to the μ-oxo dititanium compounds [TiX2μ-{η5-C5H4(η-OSiMeCl)}]2 (X=Cl, CH2Ph). All of the new complexes were characterized by elemental analysis and NMR spectroscopy.
