Abstract:
The present invention relates to a ligand compound, a catalyst system for ethylene oligomerization, and a method for ethylene oligomerization using the same. The catalyst system for ethylene oligomerization according to the present invention not only has excellent catalytic activity but also shows more improved liquid olefin selectivity, and enables more effective preparation of an alpha-olefin through the oligomerization of ethylene because it is particularly possible to control the selectivity to 1-hexene or 1-octene.
