摘要

A series of α-diimine nickel(II) complexes containing chloro-substituted ligands, [(Ar)N=C(C10H 6)C=N(Ar)]NiBr2 (4a, Ar = 2,3-C6H 3Cl2; 4b, Ar = 2,4-C6H3C1 2; 4c, Ar = 2,5-C6H3Cl2; 4d, Ar = 2,6-C6H3Cl2; 4e, Ar = 2,4,6-C6H 2Cl3) and [(Ar)N=C(C10H 6)C=N(Ar)]2NiBr2 (5a, Ar = 2,3-C 6H3Cl2; 5b, Ar = 2,4-C6H 3Cl2; 5c, Ar = 2,5-C6H3Cl 2), have been synthesized and investigated as precatalysts for ethylene polymerization. In the presence of modified methylaluminoxane (MMAO) as a cocatalyst, these complexes are highly effective catalysts for the oligomerization or polymerization of ethylene under mild conditions. The catalyst activity and the properties of the products were strongly affected by the aryl-substituents of the ligands used. Depending on the catalyst structure, it is possible to obtain the products ranging from linear α-olefins to high-molecular weight polyethylenes.
