Iron (II) complexes with hyperbranched salicylaldimine ligands: Synthesis, characterization and ethylene oligomerization

A series of iron (II) complexes with hyperbranched salicylaldimine ligand have been synthesized and characterized. The complexes, upon activation by MAO, can catalyze ethylene oligomerization with activities up to 9.19 × 104 g/mol Fe·h at 25 °C.62
