A catalytic composition comprising at least one nickel compound mixed or complexed with at least one tertiary phosphine or a phosphite carrying a functional group, at least partly dissolved in a non-aqueous medium with an ionic nature resulting from bringing at least one aluminum halide into contact with at least one quaternary ammonium halide and/or at least one quaternary phosphonium halide is useful for dimerizing, co-dimerizing and oligomerizing olefins. Functional group include, but are not limited to, an amine, a cyclic amine, a nitrogen-containing heterocycle, an ester, an acid, an alcohol, a quaternary ammonium, a quaternary phosphonium, a sulfonium, a sulfonate or a phosphonate group.
一种由至少一种镍化合物与至少一种带官能团的叔膦或亚磷酸酯混合或络合而成的催化组合物,至少部分溶解在一种非水介质中,该介质具有离子性质,是通过使至少一种卤化铝与至少一种季铵卤化物和/或至少一种季膦卤化物接触而产生的,可用于烯烃的二聚化、共二聚化和低聚化。官能团包括但不限于胺、环胺、含氮杂环、酯、酸、醇、季铵、季鏻、锍、磺酸盐或膦酸盐基团。
