摘要
The reaction of the lithium salt of backbone fluorinated beta-diketiminate ligands, ArNC(CF3)CHC(CF3) NArLi, with trans-[NiCl(Ph)(PPh3)(2)] gives nickel (II) complexes, ArNC(CF3)CHC(CF3)NAr(Ph) (PPh3)Ni (Ar = 2,6-Me2C6H3: 1; 2,6-(Pr2C6H3)-Pr-i:2). When activated by methylaluminoxane (MAO), both complexes polymerize norbornene rapidly via a vinyl-type polymerization mechanism. Treatment of nickel complex I with oxygen gives rise to intramolecular aerobic hydroxylation. The oxygenated species 3 was characterized by X-ray crystallography.
