Abstract:A series of dimeric titanium complexes bearing salicylaldiminates, [4-R-6-(t)Bu-2-(CH=N(n)Bu)C(6)H(2)OTiCl(2)(mu-Cl)](2) [R = H (1); R = (t)Bu (2); R = NO(2) (3)], have been synthesized in high yield (>90%) by the reaction of corresponding 4-R-6-(t)Bu-2-(CH=N(n)Bu)C(6)H(2)OSiMe(3) with TiCl(4). The molecular structure of 2 has been confirmed by single-crystal X-ray diffraction analysis. When activated with methylaluminoxane, these complexes exhibit good catalytic activity for ethylene polymerization.
