The present invention provides a method of producing oligomers of olefins, comprising reacting olefins with a chromium based catalyst under oligomerization conditions. The catalyst can be the product of the combination of a chromium compound and a pyridyl bis(oxazoline) or pyridyl bis(thiazoline) ligand. In particular embodiments, the catalyst composition can be used to dimerize ethylene to butenes.
