Cobalt and Nickel Complexes Bearing 2,6-Bis(imino)phenoxy Ligands:Synthesis and Ethylene Oligomerization Study

Abstract

A series of new cobalt and nickel complexes MLX₂ (M = Co or Ni, X = Cl) bearing 2,6-bis(imino)phenoxy ligands have been synthesized. Treatment of the complexes with methylaluminoxane (MAO) leads to active catalysts for ethylene oligomerization. The oligomers are olefins from C₄ to C₆.
