| 中文摘要 | a series of neutral nickel complexes [6-chn(2,6-(pr2c6h3)-pr-i)-2-(2-no2c6h4)-c6h3o-kappa(2)- n,o]ni(ph)(pph3) (6a), [6-chn(2,6-(pr2c6h3)-pr-i)-2-(c6f5)-c6h3o-kappa(2)-n,o]ni(r)(l) (r = ph, l = pph3 (6b-pph3); r = me, l = pyridine (6b-py); r = ch2ph, l = pme3 (6b-(1)bz); r = eta(3)-ch2ph (6b-(3)bz)), and [6-chn(2,6-(pr2c6h3)-pr-i)-2-(2-och3c6h4)-c6h3o-kappa(2)-n,o]ni(ph)(pph3) (6c) based on 2-nitrophenyl-, pentafluorophenyl-, and 2-methoxyphenyl-substituted salicylaldimine ligands, respectively, have been synthesized and characterized by h-1 nmr, c-13 nmr, and elemental analysis. the solid structures of 6a, 6b-pph3, 6b-py, and 6b-(1)bz have been further confirmed by x-ray crystallography. by combining the benefits of both electronic and steric factors, all the complexes with electron-withdrawing groups proved to be highly active single-component catalysts for ethylene polymerization, producing polymer with moderate molecular weights. among these catalysts, 6b-pph3 exhibited very high productivity of up to 5.87 x 10(6) g pe/mol(ni) . h under optimal conditions. compared with 6b-pph3 and 6b-py, 6b-(3)bz requires lower temperature and ethylene pressure to show high productivity. the branching number, m-w, and t-m of the polymer can be readily manipulated by variation of reaction conditions and catalyst structure. |
