Catalytic composition for dimerizing, co-dimerizing and oligomerizing olefins

   
   

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 groups 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.

Una composizione catalitica che contiene almeno un mixed compound del nichel o complessato con almeno una fosfina terziaria o un fosfito che trasporta un gruppo funzionale, dissolto almeno parzialmente in un mezzo non acquoso con una natura ionica derivando dal mettere almeno un alogenuro di alluminio in contatto con almeno un alogenuro dell'ammonio quaternario e/o almeno un alogenuro quaternario del fosfonio, รจ utile per dimerizing, il co-dimerizing-dimerizing e le olefine oligomerizing. I gruppi funzionali includono, ma non sono limitati a, un'ammina, un'ammina ciclica, un heterocycle contenente azoto, un estere, un acido, un alcool, un ammonio quaternario, un fosfonio quaternario, un sulfonium, un solfonato o un gruppo del phosphonate.
