2-(R-1H-Benzoimidazol-2-yl)-6-(1-aryliminoethyl)pyridyliron(II) dichlorides: Synthesis, characterization and the ethylene oligomerization behavior

► 2-(Me-1H-benzoimidazol-2-yl)-6-(1-aryliminoethyl)pyridyliron dichlorides (Fe1-Fe6). ► 2-(Cl-1H-benzoimidazol-2-yl)-6-(1-aryliminoethyl)pyridyliron dichlorides (Fe7-Fe12). ► Fe1-Fe6 gave high activities in ethylene oligomerization when activated by MMAO. ► Fe7-Fe12 showed high activities in ethylene oligomerization in presence of MAO. ► Oligomers formed were high selectivity for α-olefins and high K values.
