英文摘要: The catalytic performance of Ni(eta(5)-Ind)(2) complex in the dimerization of propylene was studied in combination with an organoaluminum co-catalyst, eventually in the presence of a phosphine ligand. The effects of the type of aluminum co-catalyst and its relative amount, the nature of phosphine ligand and P/Ni ratio as well as the reaction temperature were examined. The results indicated that the nickel precatalyst exhibited high productivity for the propylene dimerization together with organoaluminum. It was likely to strongly modify the reactivity in the catalytic system when using phosphine ligand as additives, especially at the reaction temperature below 0degreesC. The catalytic system based on Ni(eta(5)-Ind)(2) complex displayed an extremely high productivity (TOF up to 169000 h(-1)) and a good regioselectivity to 2,3-dimethylbutenes (2,3-DMB) in dimers (66.4%) under proper reaction parameters.
