Abstract

A process for oligomerization of ethylene, comprising subjecting a catalyst composition to a gas phase of ethylene and conducting an oligomerization, wherein the catalyst composition comprises (a) a chromium compound, (b) a metalated ligand, and (c) an activator or cocatalyst; and catalyst composition as well as a metalated ligand.
