Abstract

Official abstract text for this publication.

The present invention relates to a ligand compound, a catalyst system for olefin oligomerization, and a method for oligomerizing olefins using the same. The ligand compound according to the present invention has a structure in which a substituent is substituted in the trans form, and thereby when used for olefin oligomerization, the activity of the catalyst used and the selectivity of 1-hexene and 1-octene can be increased.

First claim

Opening claim text (preview).

The invention claimed is: 1. A compound represented by Chemical Formula 1 or 2 below: in Chemical Formulas 1 and 2, R 1 to R 4 are each independently C 1-10 alkyl; C 3-6 cycloalkyl unsubstituted or substituted by C 1-10 alkyl or C 1-10 alkoxy; C 6-20 aryl unsubstituted or substituted by C 1-10 alkyl or C 1-10 alkoxy; Or C 5-20 heteroaryl unsubstituted or substituted by C 1-10 alkyl or C 1-10 alkoxy, R 5 is C 3-6 cycloalkyl unsubstituted or substituted by C 1-10 alkyl or C 1-10 alkoxy; C 6-20 aryl unsubstituted or substituted by C 1-10 alkyl or C 1-10 alkoxy; or C 5-20 heteroaryl unsubstituted or substituted by C 1-10 alkyl or C 1-10 alkoxy, and X is a bond or C 1-5 alkylene. 2. The compound of claim 1 , wherein R 1 to R 4 are identical to one another. 3. The compound of claim 1 , wherein R 1 to R 4 are phenyl. 4. The compound of claim 1 , wherein R 5 is cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cyclohexyl substituted with methyl, or phenyl. 5. The compound of claim 1 , wherein X is a bond or methylene. 6. The compound of claim 1 , wherein R 5 is C 3-6 cycloalkyl, or C 6-20 aryl, and X is methylene. 7. The compound of claim 1 , wherein R 5 is C 3-6 cycloalkyl, and X is a bond. 8. The compound of claim 1 , wherein the compound represented by Chemical Formula 1 or 2 is any one selected from the group consisting of the following compounds: 9. A catalyst system for olefin oligomerization, comprising: the compound of claim 1 , a source of transition metal, and a cocatalyst. 10. A method for oligomerizing olefins, comprising multimerizing olefins in the presence of the catalyst system for olefin oligomerization of claim 9 .
