PROBLEM TO BE SOLVED: To make it possible to obtain highly selectively and efficiently the subject compound, especially ethylene trimer in a high yield, by reacting a specific transition metal compound and an aluminum compound with an α-olefin. SOLUTION: An α-olefin is reacted in the presence of (A) a compound represented by the formula MX<1> X<2> (TR<1> R<2> R<3> )k [M is a transition metal; X<1> and X<2> are each H, a halogen or a (substituted)(branched)alkyl; R<1> to R<3> are each H, OH, a (substituted)(branched)alkyl, etc.; and may mutually be bonded to form a ring or a cross-linkage or two may be united to form an alkylidene, etc.; T is N, P or O; (k) is 2 or 4] [e.g. bis(triphenylphosphine)nickel(II) bromide] and (B) a compound represented by the formula R<4> m Al(OR<5> )n X<3> p Hq R<4> and R<5> are each a 1-15C hydrocarbon group; X<3> is a halogen; 0<(m)<=3; 0<=(n)<3; 0<=(p)<3; 0<=(q)<3; [(m)+(n)+(p)+(q)] is 3} (e.g. methylaluminum dichloride). |
