| 英文摘要 | A series of novel (arylimido)vanadium(V) complexes bearing tridentate salicylaldiminato chelating ligands, V(N-2,6-Me2C6H3)Cl-2[(O-2-Bu-t-4-R-C6H3)CH=ND] (R = H, D = 2CH(3)O-C6H4 (2a); 2-CH3S-C6H4 (2b); 2-Ph2P-C6H4 (2c); 8-C9H6N (quinoline) (2d); CH2C5H4N (2e); R = Bu-t, D = 2-Ph2P-C6H4 (2f)), were prepared from V(NAr)Cl-3 by reacting with 1.0 equiv of the ligands in the presence of triethylamine in tetrahydrofuran. These complexes were characterized by H-1, C-13, P-31, and V-51 NMR spectra and elemental analysis. The structures of 2c and 2f were further confirmed by X-ray crystallographic analysis. These (arylimido) vanadium(V) complexes are effective catalyst precursors for ethylene polymerization in the presence of Et2AlCl as a cocatalyst and ethyl trichloroacetate as a reactivating agent. Complex 2c with a -PPh2 group in the sidearm was found to exhibit an exceptional activity up to 133800 kg polyethylene/molV h for ethylene polymerization at 75 degrees C, which is one of the highest activities displayed by homogeneous vanadium( V) catalysts at high temperature. Moreover, high molecular weight polymers with unimodal molecular weight distribution can be obtained, indicating the single site behavior of these catalysts. (C) 2014 Wiley Periodicals, Inc. |
