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.
本发明涉及一种用于选择性寡聚烯烃的方法,包括将烯烃与:1)至少一种二芳基取代的二
膦配体;2)
铬金属前体;以及3)可选地,一个或多个活化剂接触。在一个特定实施例中,用于选择性寡聚烯烃的方法包括三聚
乙烯以选择性地形成
1-己烯。
