  Ethylene oligomerization catalyzed by a novel iron complex containing fluoro and methyl substituents

  摘要：

  A novel 2,6-bis(imino)pyridyl iron complex, [2,6-(2-F-4-CH3C6H3N=CCH3)(2)C5H3N]FeCl2.H2O (3) has been synthesized by the reaction of the corresponding bis(imino)pyridyl ligand with FeCl2.4H(2)O in tetrahydrofuran (THF). The activity of complex 3 reaches to 10(7) g/mol Fe h in ethylene oligomerization, and the products are mostly (>90%) 1-butene, 1-hexene and 1-octene. As reaction temperature increases, the activities decrease rapidly and the product distributions shift to the low-molecular-weight part. The product distributions are almost unchanged when the Al/Fe molar ratio increases from 420 to 2500, but the catalytic activities increase rapidly at first and then decrease. Other three complexes (2,6-(2-X-4-Y-6-ZC(6)H(3)N=CCH3)(2)C5H3N}FeCl2.nH(2)O (X = CH3, Y = CH3, Z = H, n = 0 (1), X = F, Y = H, Z = F, it = 1 (2)) and {Fe[2,6-(2-FC6H3N=CCH3)(2)C5H3N}(2)](2), [FeCl4](2)(-).H2O (4) have been also synthesized for comparison and used for ethylene oligomerization. The ortho and para substituents on aniline have performed effects on oligomerization activities and distributions of oligomers for 2,6-bis(imino)pyridyl iron complexes. (C) 2004 Elsevier B.V.

  A series of novel bis(imino)pyridine cobalt(II) chlorides, LCoCl2, with the bis(imino)pyridine ligands bearing one or several electron-withdrawing substituents (F, Cl, Br, CF3) at the aniline moieties, have been prepared and characterized. In the presence of methylalumoxane (MAO), these complexes have demonstrated high ethylene oligo- and polymerization activity (up to 1.8·107 g products∙(mol Co)−1 h−1 bar−1)

  containing either electron withdrawing or electron donating substituents in their ligand frameworks was synthesized and characterized. After activation with methylaluminoxane (MAO), these catalysts oligomerize or polymerize ethylene to give both linear and branched products. In contrast to iron(II) complexes, the presence of at least one ortho-substituent at the iminophenyl rings is not obligative for catalytic

  analyses indicate that 1, 8, 9, and 10 are five-coordinate complexes, while 11 is an ion-pair complex with one six-coordinate iron center and one four-coordinate iron center. These metal coordinative complexes, activated by modified methylaluminoxane (MMAO), lead to highly active ethylene polymerization and/or oligomerization catalysts. The catalyst productivity and product properties crucially depended
