Graphical Abstract

Keine Liganden nötig: Rhodium-Komplexe auf HY-Zeolith als Träger katalysieren die Bildung von C-C-Bindungen über einen neuartigen Mechanismus, der eine Kooperation zwischen der Metallspezies und Brønsted-Säurezentren des Zeolithträgers umfasst (siehe Bild). Der Katalysator agiert in Abwesenheit von Liganden wie Halogeniden und zeigt eine hohe Selektivität für n-Butene, sogar in einem Überschuss an H2.
