摘要：
Three new neutral monoamidinate nickel complexes [(2,6-Pr-i-C6H3)N=C(Ar-1)-N(Ar-2)]Ni(Ph)(PPh3) (1, Ar-1 phenyl, Ar-2 = 2,6-diispropyphenyl: 2, Ar-1 = p-tolyl, Ar-2 = 2,6-dimethylphenyl; 3, Ar-1 = p-tolyl, Ar-2 pentafluorophenyl) have been synthesized and characterized. The molecular structure of 3 has been determined by X-ray diffraction analysis. The nickel complexes activated with MAO were found to exhibit very high activity, up to 1.94 x 10(7) g PNBE/(mol Ni h), for vinyl-addition polymerization of norbornene and oligomerize ethylene producing a mixture of dinners and trimers; with a moderate turnover frequency.
