Abstract
A series of 2-(1 H -benzo[ d ]imidazol-2-yl)- N -benzylidenequinolin-8-amines was synthesized and characterized. They are stable as solids while displaying a tendency to decompose in solution. On reaction with NiCl 2 , different coordination pattern sets of L·NiCl 2 or [L 2 Ni] 2+ ·2Cl − are obtainable in THF or ethanol. When activated by Et 2 AlCl, the complexes L·NiCl 2 exhibit good to high catalytic activities and selectivities for 1-C 4 in ethylene oligomerization, while the complexes [L2Ni] 2+ ·2Cl − hardly showed any activity, which is attributable to nickel coordination by two ligands barring interaction of ethylene with the metal center.
