Ligands and catalyst systems thereof for ethylene oligomerization to linear alpha olefins

Abstract

Ligands of formula (V); bis-aryliminepyridine MXn complexes comprising a ligand of formula (V), wherein M is a metal selected from Fe and Co, n is 2 or 3, and X is halide, optionally substituted hydrocarbyl, alkoxide, amide, or hydride; [bis-aryliminepyridine MYp.Ln+] [NC31 ]q complexes, comprising a ligand of formula (V), wherein Y is a ligand which may insert an olefin, M is Fe or Co, NC− is a non-coordinating anion and p+q is 2 or 3, matching the formal oxidation of the metal atom M, L is a neutral Lewis donor molecule and n=0, 1, or 2; and processes for the production of alpha-olefins from ethylene, using said complexes.
