Abstract

AbstractA series of tridentate aryloxy‐based ligands were synthesized and characterized for their coordination behaviour towards TiIV. Coordination studies revealed that the nature of the central atom (amine vs. ether) and the type of bridging spacer (aromatic vs. aliphatic) are important aryloxy ligand parameters and influence the ligand coordination mode and the formation of stable titanium complexes. This series of titanium complexes were evaluated in ethylene oligomerization and polymerization after activation with methylaluminoxane (MAO) and showed the preferential formation of polyethylene. In some cases, the formation of a small amount of 1‐hexene suggests the existence of several catalytic centres in the reaction mixture.
