英文摘要	The cobalt(II) chloride complexes, [2-(C7H4N2H)-8-(ArN)C10H8N]CoCl2 (Ar = 2,6-Me2C6H3 Co1; 2,6-Et2C6H3 Co2; 2,6-i-Pr2C6H3 Co3; 2,4,6-Me3C6H2 Co4; 2,6-Et-2-4-MeC6H2 Co5; Bu3C6H2 Co-6), have each been prepared by a one-pot template reaction of 2-benzoimidazoly1-5,6,7-trihydroquinolin-8-one with the corresponding aniline in the presence of cobalt dichloride. The molecular structures of the methanol adducts, Co1(HOMe) and Co4(HOMe), reveal distorted octahedral geometries that self-assemble to form networks based on NH center dot center dot center dot Cl and OH center dot center dot center dot Cl intermolecular hydrogen bonding interactions. On activatin with methylaluminoxane (MAO), all six cobalt complexes catalyzed ethylene dimerization with a high selectivity for 1-butene. By marked contrast, with modified methylaluminoxane (MMAO), products the result of ethylene dimerization and trimerization were observed with a bias toward the C-6 products (up to 49% 1-hexene). In general, the MMAO-promoted oligomerizations display higher catalytic activities with mesityl-containing Co4 the stand-out performer [7.60 X 10(5) g.mol(-1) (Co) h(-1) at 50 degrees C].
