| 英文摘要 | Series of 2-R(1)-6-(1-R(2)-4,5-diphenyl-1H-imidazol-2-yl)pyridine (R(1) = R(2) = H, L1; R(1) = Me, R(2) = H, L2; R(1) = H, R(2) = Me, L3; R(1) = R(2) = Me, L4), 2-(6-R(1)-pyridin-2-yl)-1H-phenanthro[9,10-d]imidazole (R(1) = H, L5; R(1) = Me, L6) and 2-(pyridin-2-yl)phenanthro[9,10-d]oxazole (L7) were synthesized and used to prepare their corresponding dihalonickel complexes (C1-C9). All organic compounds and nickel complexes were characterized by elemental and spectroscopic analyses. Molecular structures of C1, C4, C5 and C8 were confirmed by the single-crystal X-ray diffraction analysis. The single-crystal X-ray analysis revealed complex C1 as a distorted octahedral geometry, complex C4 as a distorted square pyramidal geometry, complex C5 as a distorted trigonal bipyramidal configuration, and complex C8 as a tetrahedral geometry. Upon activation with methylaluminoxane (MAO), the nickel complexes showed good activity towards norbornene polymerization through main additional and minor ring-opening metathesis. The reaction parameters such as norbornene concentration, reaction temperature and different coordinate environments caused by the ligands affected their catalytic performances.
