| 英文摘要 | Four titanium complexes having beta-ketoiminate chelate ligands with fluorine or alkyl groups [(Ar)NC(CH3)C(H)C(CH3)O](2)TiCl2 (3a: Ar=2.6-F2C6H3; 3b: Ar=C6F5: 3c: Ar=2.6-Me2C6H3; 3d: Ar = 2.6-(Pr2C6H3)-Pr-i) have been synthesized and characterized by H-1 NMR and EA. Complexes 3a, 3c and 3d were further characterized by X-ray diffraction analysis and demonstrated distorted octahedral coordination structure around the titanium center. The substituents in ligands greatly affect the coordination mode, resulting in three different isomeric structures. These complexes are active catalysts for polymerization of ethylene with MMAO as cocatalyst. The substituents in ligands have also great influences on catalytic activity. The complexes with alkyl groups have lower activity, while the complexes with fluorine atoms have middle or high catalytic activity. (C) 2009 Elsevier B.V. All rights reserved. |
