AbstractA series of tridentate N boolean AND N boolean AND N iron(II) and cobalt(II) complexes containing N-((pyridin-2-yl) methylene)-quinolin-8-amine derivatives were synthesized and characterized by elemental and spectroscopic analyses. The molecular structure of 1a was con. rmed by X-ray diffraction analyses. On treatment with modified methylaluminoxane, these metal complexes exhibited good catalytic activities up to 2.8 x 10(6) g mol(-1)(Fe) h(-1) for ethylene oligomerization, and butenes were the major products with nice selectivity for 1-C-4. The steric and electronic effects on catalytic activities of metal complexes were carefully investigated as well as the influence of various reaction parameters. In the catalytic system, Fe(II) complexes performed better catalytic activities than their Co(II) analogues. With ligands having bulky substituents, the better catalytic activity was observed in catalytic system of Fe(II) complex, however, the lower catalytic activity was obtained in catalytic system of Co(II) complexes.
