  tert-Butylsilylcyclopentadienyl Group 4 metal complexes

  摘要：

  New Group 4 metal t-butyldimethylsilyleyclopentadienyl complexes [MCpCp'Cl-2] (Cp = eta(5)-C5H5 : Cp' = eta(5)'-C5H4SiMe2',Bu; M = Ti 4, Zr 5, Hf 6) were prepared by reaction of 1 equiv. of the lithium (2) and thallium (3) salts of t-butyldimethylsilylcyclopentadiene I with the monocyclopentadienyl complexes [MCpCl3. DME] (M = Zr, Hf) and [TiCpCl3], respectively, A similar reaction using ZrCl4(THF)2 and HfCl4 with 2 equiv. of the lithium salt 2 gave the symmetric [MCp2Cl2] (M = Zr 7, Hf8) rnetallocenes. Alkylation of these compounds with 2 equiv. of MgRCl (R = Me. CH2Ph) and Li(CH2CMe2Ph) afforded the dialkyl complexes [MCpCp'R-2] (R = Me, M = Zr 9, Hf 10: R = CH2Ph. M = Ti 11. Zr 12. Hf 13). [ZrCp2(CH2Ph):] 14 and [ZrCpCp'(CH2CMe2Ph)(2)] 17, A Similar reaction of 5 with 1 equiv. of Mg(CH2Ph)Cl gave the monobenzyl compound [ZrCpCp'Cl(CH2Ph)] (15), Hydrolysis of 15 with a stoichiometric amount of water afforded the dinuclear mu-oxo compound [(ZrCpCp'Cl)(2)(mu-O)] (16). All of the new complexes reported were characterized by elemental analysis and H-1 and C-13 NMR spectroscopy and the molecular structures of 4 and 16 were determined by X-ray diffraction methods. Ethylene polymerization activities were measured for compounds 4-7. (C) 2002 Elsevier Science B.V. All rights reserved.
