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

Claim (Index 1):
A catalyst system for olefin oligomerization comprising: a ligand compound represented by Chemical Formula 1 below;\n a transition metal source; and a cocatalyst: in the above Chemical Formula 1, E 1  and E 2  are each independently an element selected from the group consisting of boron (B), nitrogen (N), oxygen (O), silicon (Si), phosphorus (P), and sulfur (S), and R 1  to R 6  each independently represent hydrogen, an alkyl group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 20 carbon atoms, an alkylsilyl group having 1 to 20 carbon atoms, a haloalkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 40 carbon atoms, an arylalkyl group having 7 to 20 carbon atoms, an arylsilyl group having 6 to 20 carbon atoms, an alkylaryl group having 7 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, an alkylsiloxy group having 1 to 20 carbon atoms, an aryloxy group having 6 to 20 carbon atoms, a halogen group, or an amino group.
