Abstract
The present invention relates to the oligomerization of lower alpha olefins, and particularly ethylene, to higher olefins in the presence of a catalyst precursor having either or both of a dithiophosphinate complex and a heterobifunctional ligand having a phosphine center and an imine or similar center, in the presence of an activator. The catalysts have a high reactivity and a good selectivity.
