Abstract: The present invention relates to a chrome compound composed of non-coordinating anions and a trivalent chrome cation, a reactant of the chrome compound and a bidentate ligand, an ethylene oligomerization reaction catalyst system using the chrome compound and the reactant, and a method for preparing an ethylene oligomer using the catalyst system. Through the above conformation, the present invention can selectively produce 1-hexene and 1-octene with high activity while omitting the use of methylaluminoxane (MAO), and can provide an ethylene oligomerization process more suitable for mass production.
