英文摘要	A series of (imido)vanadium(V) dichloride complexes containing 8-(2,6-dimethylanilide)-5,6,7-trihydroquinoline ligands of the type V(NR)Cl-2[8-(2,6-Me2C6H3)N(C9H10N)] (R = Ad (3), 2-MeC6H4 (4), 2,6-Me2C6H3 (Ar, 5)) have been prepared and identified, and their structures have been determined by X-ray crystallographic analysis. The ethylene dimerization catalyst generated from complex 3 upon treatment with an excess amount of MAO exhibited remarkable catalytic activities (e.g. TOF = 9600000 h(-1) (2670 s(-1)), Al/V = 4000 (molar ratio)), affording 1-butene as the major product (95.0-99.4%). The activities of 3 and 4 were higher than those exhibited by the corresponding 2-(anilide)methylpyridine analogues; 3 showed higher 1-butene selectivity than the others and the activity did not decrease remarkably at 50 degrees C. Complex 5 afforded a mixture of polymer and oligomers with low activities, suggesting that a fine tuning of both the imido and the anionic donor ligands plays an essential role in this catalysis.
