Ethylene Oligomerization Using Bis(imino)pyridinecobalt(II) Complexes Immobilized in Fluorotetrasilicic Mica Interlayer as Heterogeneous Catalysts

Ethylene Oligomerization Using Bis(imino)pyridinecobalt(II) Complexes Immobilized in Fluorotetrasilicic Mica Interlayer as Heterogeneous Catalysts

Heterogeneous bis(imino)pyridinecobalt(II) catalysts were prepared by direct reaction of cobalt-ion-exchanged fluorotetrasilicic mica and a bis(imino)pyridine ligand. The catalyst prepared from the ligand with 2-CF3Ph groups on the imino nitrogen showed high activity in ethylene oligomerization, wit...

Zusammenfassung:Heterogeneous bis(imino)pyridinecobalt(II) catalysts were prepared by direct reaction of cobalt-ion-exchanged fluorotetrasilicic mica and a bis(imino)pyridine ligand. The catalyst prepared from the ligand with 2-CF3Ph groups on the imino nitrogen showed high activity in ethylene oligomerization, with excellent selectivity for α-olefins.
