Paragraph 0212; 0214, (2018/11/22)
PROBLEM TO BE SOLVED: To provide a novel transition metal compound, a catalyst for olefin multimerization containing the compound and having excellent activity and selectivity, and a method for producing an olefin multimer that is performed in the presence of the catalyst for olefin multimerization. SOLUTION: The present invention provides a transition metal compound of general formula (1), a catalyst for olefin polymerization containing the same, and a method for producing an olefin polymer with the catalyst (R1-R6 are a hydrogen atom or the like, M is a transition metal atom in the periodic table group 6, n is a valence of M, X is a halogen atom or the like, Y is an oxygen atom or the like, Z is a hydrocarbon group or the like).

Reaction of a trimethyl titanium complex, (FI)TiMe3 (FI = phenoxy-imine), with 1 equiv of B(C6F5)3 gives [(FI)TiMe2][MeB(C6F5)3], an effective precatalyst for the selective trimerization of ethylene. Mechanistic studies indicate that catalyst initiation involves generation of an active TiII species by olefin insertion into a Ti-Me bond, followed by β-H elimination and reductive elimination of methane, and that initiation is slow relative to trimerization. (FI)TiMe3/B(C6F 5)3 also leads to a competent catalyst for the oligomerization of α-olefins, displaying high selectivity for trimers (>95%), approximately 85% of which are one regioisomer. This catalyst system thus shows promise for selectively converting light α-olefins into transportation fuels and lubricants.
