- W2314104080 abstract "A series of novel eight-coordinate dichloride zirconium complexes with the general formula L2ZrCl2 supported by two tridentate [ONN] ligands have been synthesized by the reaction of ZrCl4·2THF with 2 equiv of the corresponding ligands (tridentate phenoxy-imine ligands (L1H–L4H) or tridentate phenoxy-amine ligands (L5H and L6H)). These complexes were characterized by NMR and elemental analyses. The molecular structures of representative zirconium complexes C2 and C6 were confirmed by single-crystal X-ray diffraction and revealed that the metal center is eight-coordinated by two tridentate [ONN] ligands and two chlorides in a distorted-square-antiprismatic geometry. When C1–C6 were activated by modified methylaluminoxane (MMAO), the resultant catalysts displayed notable thermal stability and high activities toward ethylene polymerization. The ligand substituents, the metal coordination environment, and the reaction conditions had a profound effect on the polymerization. The catalytic activity increases consistently with increasing polymerization temperature, and the highest activity of 1.04 × 106 g of PE (mol of Zr)−1 h–1 was achieved in o-xylene at 140 °C. A catalytic lifetime of nearly 5 h was observed for the C5/MMAO catalyst system at 140 °C." @default.
