摘要：

This paper reports the synthesis and characterization of four neutral chromium(III) complexes bearing N,O,N'-tridentate ligands, [LCrCl3], (L = 2-[(2-pyridylmethoxy)methyl]pyridine, 1; L = 8-(2-pyridylmethoxy) quinoline, 2; L = 8-[(2-pyridylmethoxy)methyl]quinoline, 3; L = 8-(quinolin-8-ylmethoxy)quinoline,4). Molecular structures of 1-3 have been determined by X-ray crystallography, which show that L-1 and L-3 exhibit facial configuration in 1 and 3 while L-2 adopts meridional arrangement in 2. The ethylene polymerization experiments show that complexes 1-4 are moderately active precatalysts for ethylene polymerization with activation with MAO. (C) 2012 Elsevier B.V. All rights reserved.
