Abstract:
This invention relates to a method to selectively oligomerize olefins comprising contacting olefins with: 1) at least one diaryl-substituted diphosphine ligand; 2) a chromium metal precursor; and 3) optionally, one or more activators. In a particular embodiment, the method for selectively oligomerizing olefins includes trimerizing ethylene to selectively form 1-hexene.
