| 英文摘要 | The synthesis of the substituted silyl cyclopentadiene ligand (C5H5)Si(CH3)(2)(C6H5) ((CpH)-H-Si) (1) is described. Deprotonation of (1) gives ((CpLi)-Li-Si) (2) which reacts with CrCl3 to produce the chloro-bridged complex [(eta(5)-Cp-Si)Cr(mu-Cl)Cl](2) (3). Single-crystal X-ray structure analysis reveals that a centrosymmetric dimer exists in the solid state. When activated with methylaluminoxane (MAO), complex (3) exhibits several interesting features as a catalyst for ethylene polymerization. With the help of a semi-empirical MO calculation, a cationic sandwich intermediate structure in the catalytic process was proposed. (C) 2002 Elsevier Science Ltd. All rights reserved. |
