Iron bis(arylimino)pyridine precursors activated to catalyze ethylene oligomerization as studied by DFT and QSAR approaches

In addition, a quantitative structure activity relationship (QSAR) has been built comprising in total 10 different precursors. From this correlation it follows that the position of the aryl groups in the bis(arylimino)pyridyl complexes plays an important role with respect to the activity of the catalysts.
