摘要

Bidentate monoanionic ligands 2-(benzo[d]thiazol-2-yl) phenol (La), 2-(benzo[d]thiazol-2-yl)-6-methylphenol (Lb), 2-(benzo[d]thiazol-2-yl)-6-tert-butyl-4-methylphenol (Lc), 2-(benzo[d]thiazol-2-yl)-6-chlorophenol (Ld), and 2-(benzo[d]thiazol-2-yl)-4-chlorophenol (Le) have been synthesized.Reactions of TiCl_4(THF)_2or ZrCl_4withLa-Leafford the corresponding titanium complexes Ti[ON]_2~RCl_2[R = 6-Me (2b); 4-Me-Bu~t(2c)], and zirconium complexes Zr[ON]_H 3a);R = 6-Me (3b); R = 4-Me-6-Bu~t (3c); R = 6-Cl (3d);R= 4-Cl (3e)], and Zr[ON~R]HCl_4 THF [R = 6-Me(4b)], respectively. Complexes 2a-4b were characterized by IR, 1H NMR spectra and elemental analysis.The molecular structures of La, 2b, 2c, 3b, 3c and 4b have been characterized by single-crystal X-ray diffraction analyses. The effect of steric hindrance and the coordination metal on the structure of theproducts has been investigated. When activated by excess methylaluminoxane (MAO), 2b and 2c, 3a-3eand 4b can be used as catalysts for ethylene polymerization and exhibit moderate to good activities.
