PROBLEM TO BE SOLVED: To efficiently and highly selectively produce 1-hexene from ethylene. SOLUTION: An ethylene trimerization catalyst comprises a transition metal complex with a coordinated neutral multidentate ligand having a tripod type structure, represented by the formula LCrXn (L is a neutral multidentate ligand having a tripod type structure; X is one or more kinds selected from a group consisting of a halogen atom, an amide group, a sulphonyl group, and an alkoxy group; M is a transition metal complex among group 3-10 in the periodic table; and n is an integer equal to the oxidation number of the transition metal complex M), an alkyl metal compound, and radical anions. |
