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