摘要:
The novel chloro(1-naphthyl) [8-(diphenylphosphino) quinoline] nickel(II) (1), chloro(1-naphthyl) [2-methyl-8( diphenylphosphino) quinoline] nickel(II) (2), and [2-methyl-8- (diphenylphosphino) quinoline] nickel(II) dichloride ( 3) complexes were synthesized in satisfactory yield and fully characterized. The structures of complexes 1 and 3 were determined by single crystal X-ray analysis, which indicated that complex 1 exists in a square planar configuration, while complex 3 is dimeric square pyramidal. In the presence of MAO cocatalyst, complexes 1 3 displayed good catalytic activities for ethylene oligomerization in toluene, up to 2.45 x 10(5) g ethylene ( mol Ni.h.atm)(-1) by complex 3.
