Cr-catalyzed ionic liquid-organic biphasic ethylene dimerization was realized with 100% 1-butene selectivity. The perfect α-olefin selectivity can be rationalized in terms of the poor solubility of the oligomerized long-chain olefins in ionic liquids, and enables the establishment of a dimerization process without any complicated and energy-intensive catalyst and byproduct separation processes.
