Inorganic ChemistryGeneral Chemistrydescription
A series of nickel complexes bearing N,N-bidentate ligands has been synthesized and characterized by elemental analysis and infrared (IR) spectroscopy. High ethylene dimerization activity, reaching 2.43 × 106 g mol−1(Ni)h−1, was achieved by using these complexes as precatalysts activated with Me2AlCl. Moreover, the selectivity to obtain α-C4 was high (93%–96%). Comparing with the previous report by our group, the higher activity and selectivity may be attributed to the substituent at the 2-position within the ligand, creating the steric hindrance around the metal atom.
