Abstract：The novel ligand, 1-benzyl-4-［o-pyridyl］-［1,2,3］-triazole(1), was synthesized via click reaction of benzyl chloride, 2-ethynylpyridine and sodium azide， using Cu(I) as the catalyst. Treatment of 1 with anhydrous FeCl2, CoCl2 or NiBr2·DME afforded the corresponding novel pyridyl-triazole metal complexes(2~4), respectively. The structures were characterized by 1H NMR, 13C NMR, IR and elemental analysis. The catalytic performance of 2~4 on ethylene polymerization indicated that 4 exhibited the highest activity with catalytic activity of 8.8 × 105 g·mol-1·h-1 under the condition of methylaluminoxane as cocatalyst, at 20 ℃ and Al/Ni ratio was 2 500/1.
