- Аннотация: A new α-diimine-type ligand - 1 was synthesized and fully characterized. It reacted with NiBr2 to form the corresponding complex which was characterized by elemental analysis and infrared spectroscopy. According to the X-ray complex crystallizes from aqueous methanol as the hydrated dimer with ionic structure (L2Ni2Br3٠2Н2О)+Br- and distorted octahedral environment of nickel atoms. Pre-catalyst, activated with either Et3Al2Cl3 or Et2AlCl, showed good activities in ethylene oligomerization. Notably high selectivity to α-olefins was achieved in the presence of Et3Al2Cl3. The addition of PPh3 to the Ni(II)-based systems enhanced the catalytic activity and switched the selectivity from terminal to internal olefins.
