Abstract
The present invention discloses post-metallocene complexes based on sterically encumbered bi- and tri-dentate naphthoxy-imine ligands. It also relates to the use of such post-metallocene complexes in the oligomerization of ethylene to selectively prepare vinyl-end capped linear alpha-olefins.
