  摘要：

  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{eta(5)-C5H4(SiMeCl2)}]. Treatment of this complex with the lithium amides LiN(SiMe3)(2) and LiNH'Bu affords [TiCl2{N(SiMe3)2}{eta(5)-C5H4(SiMeCl2)}] and [TiCl2{eta(5)-C5H4[SiMeCl(eta-N'Bu)]}], respectively. Alkylation of the trichlorotitanium derivative with 1.5 equivalents of Mg(CH2C6H5)(2)(THF)(2) leads to the tribenzyl derivative [TI(CH2C6H5)(3){eta(5)-C5H4(SiMeCl2)}]. Hydrolysis of the trichloro-and tribenzyl-complexes leads to the mu-oxo dititanium compounds [TiX2 mu-{eta(5)-C5H4(eta-OSiMeCl)}](2) (X = CI, CH2Ph). All of the new complexes were characterized by elemental analysis and NMR spectroscopy. (C) 1998 Elsevier Science S.A.

  Trimethylsilylcyclopentadienes bearing alkoxysilyl functionality, C5H4(SiMe3)(SiMe2OR), where R is Me (2), i-Pr (3) and t-Bu (4), were prepared and characterized. Methoxy derivative 2 reacts with TiCl4 giving unstable [Ti(eta(5)-C5H4SiMe2OMe)Cl-3] (5), which is slowly transformed to chlorosilyl complex [Ti(eta(5)-C5H4SiMe2Cl)Cl-3] (6) and a mixture of cyclopentadienyltitanium(IV) methoxides on heating. Fully alkoxylated derivatives of the type [Ti(eta(5)-C5H4SiMe2OR)(OR)(3)] [R = Me (7), i-Pr (8), t-Bu (9)] and Ti[eta(5)-C5H4SiMe(OMe)(2)](OMe)(3)} (10), were synthesized in low-to-moderate yields from respective chlorosilylcyclopentadienyltitanium trichlorides. All prepared alkoxysilyl compounds were characterized by spectroscopic techniques including Si-29 NMR. Polymerization activity of 7-10 in the presence of methylaluminoxane was determined and compared with [TiCp(OMe)(3)] and corresponding trimethylsilyl-substituted compounds [Ti(eta(5)-C5H4SiMe3)(OR)(3)], where R is Me, i-Pr and t-Bu. The highest conversion of styrene has been observed in systems based on [Ti(eta(5)-C5H4SiMe3)(OMe)(3)], [TiCp(OMe)(3)] and [Ti(eta(5)-C5H4SiMe3)(OBut)(3)], respectively. The new alkoxysilyl compounds 7-10 have significantly lower activity of 500-1800 kg of polystyrene/(mol Ti mol styrene h). All prepared polystyrenes showed both high melting point and high degree of syndiotacticity as determined by DSC and NMR measurements. (C) 2012 Elsevier B.V. All rights reserved.
