Among other things, this disclosure provides an olefin oligomerization system and process, the system comprising; a) a transition metal compound, b) a pyrrole compound having independently- selected C1 to C18 is organyl groups at the 2- and 5-positions, wherein at least one of the organyl group alpha-carbon atoms attached to the 2- and 5-positions of the pyrrole compound is a secondary carbon atoms; and c) a metal alkyl. For example, the 2,5-diethylpyrrole (2,5-DEP)-based catalyst systems can afford a productivity increases over unsubstituted pyrrole catalyst, systems, non-2,5-disubstituted catalyst systems, and 2,5- dimethylpyrrole (2,5-DMP) catalyst systems.
L'invention concerne, entre autres choses, un système et un procédé doligomérisation doléfines, le système comportant : a) un composé métal de transition, b) un composé pyrrole qui comporte des groupes organyles en C1 à C18 sélectionnés indépendamment aux positions 2- et 5-, au moins un des atomes de carbone alpha du groupe organyle fixés aux positions 2- et 5- du composé pyrrole étant un atome de carbone secondaire, et c) un alkyle métallique. Par exemple, les systèmes catalyseurs à base de 2,5-diéthylpyrrole (2,5-DEP) permettent une augmentation de productivité par rapport aux systèmes catalyseurs à base de pyrrole non substitué, aux systèmes catalyseurs non 2,5-disubstitués et aux systèmes catalyseurs à base de 2,5-diméthylpyrrole (2,5-DMP).
