Iron(II) coordination compounds with ω-alkenyl substituted bis(imino)pyridine ligands: Self-immobilizing catalysts for the polymerization of ethylene

Coordination compounds of iron(II)chloride with bis(imino)pyridine ligands bearing ω-alkenyl substituents were synthesized and characterized. They can be activated with methylalumoxane (MAO) and then be used as self-immobilizing catalysts for the polymerization of ethylene. The produced polyethylene has a monomodal molecular weight distribution which is in contrast to polyethylenes that are produced with the unsubstituted catalysts.

A new iron catalyst for ethylene polymerization

The iron-based catalyst 2,6-bis[1-(4-bromo-2,6-dimethylphenylimino)ethyl]- pyridineiron(II) chloride, 1, has been successfully synthesized and characterized. Its catalytic activity was evaluated for the polymerization of ethylene at different temperatures and Al/Fe ratios and compared with that of 2,6-bis[1-(2,6-dimethylphenylimino)ethyl]pyridineiron(II) chloride, 2. The results show that the catalytic activity of catalyst 1 is highly dependent on the amount of MAO used in the polymerization of ethylene and presents a maximum value at about 20°C.

Ethylene polymerization in the presence of iron(II) 2,6-bis(imine)pyridine complex: Structures of key intermediates

The structures of intermediates generated by the activation of 2,6-bis[1-(2,6-dimethylphenylimino)ethyllpyridineiron(II) chloride (1) with various cocatalysts, methylalumoxane (MAO), trimethylaluminum (TMA), and TMA in combination wilh B(C6F5)3 and Ph3CB(C6F5)4, is studied by 1H and 2HNMR spectroscopy. The 1/AlMe3 system exhibits a higher catalytic activity in ethylene polymerization than the 1/MAO system. The activity of the latter decreases sharply with a decrease in the amount of AlMe3 in MAO. Neutral Fe(II) complexes rather than cationic intermediates are suggested to be active components in both catalytic systems.
