and bis(benzimidazolyl)pyridine ligands and their respective nickel(II) dibromide complexes were synthesized and fully characterized. After activation of the nickel complexes with ethylaluminum sesquichloride showed productivity in excess of 106 (g-oligomer)(mol-Ni)−1h−1bar−1 towards ethylene oligomerization, producing butenes as major products. The bis(benzimidazolyl)pyridine nickel complexes showed
