| Research Abstract |
Heterogeneous ethylene-oligomerization catalysts were developed by immobilizing is(imino)pyridineiron(III) and alfa-diiminenickel(II) complexes into interlayer of clay minerals such as fluorotetrasilicic mica and montmorillonite interlayers. During the ethylene oligomerization, the clay mineral-immobilized bis(imino)pyridineiron(III) complexes showed extremely high activity and produced linear alfa-olefins as useful raw materials of lubricants and surfactants with high selectivity. Meanwhile, on decreasing the steric hindrance of the ligand in heterogeneous alfa-diiminenickel complexes, the molecular weight of the products dramatically decreased. Moreover, I achieved the increase of the catalytic activity by adding fluorine atoms on iminophenyl groups of the ligand.
