摘要：

Copper complexes [Cu(L")(2)] 1-4 bearing N,O-chelating beta-ketoamine ligands L" based on condensation products of 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone with aniline (L-1), alpha-naphthylamine (L-2), o-methylaniline (L-3), and p-nitroaniline (L-4), respectively, were synthesized and characterized by IR, H-1 NMR and X-ray crystallography (except 2). They were shown to catalyze the vinyl polymerization of norbornene when activated by methylaluminoxane (MAO). Both steric and electronic effects are important and influential factors contributing to the catalytic activity of the complexes with the order of 2 > 4 > 3 > 1. (c) 2005 Elsevier B.V.
