Abstract

The present invention relates to a ligand compound, a catalyst system for olefin oligomerization and a method for oligomerizing an olefin using same. The catalyst system for olefin oligomerization according to the present invention exhibits high selectivity to 1-hexene or 1-octene while having excellent catalytic activity, thus enabling more efficient preparation of alpha-olefins.
