Cooperative Bond Activation and Catalytic Reduction of Carbon Dioxide at a Group 13 Metal Center

A single‐component ambiphilic system capable of the cooperative activation of protic, hydridic and apolar HX bonds across a Group 13 metal/activated β‐diketiminato (Nacnac) ligand framework is reported. The hydride complex derived from the activation of H2 is shown to be a competent catalyst for th...

description A single‐component ambiphilic system capable of the cooperative activation of protic, hydridic and apolar HX bonds across a Group 13 metal/activated β‐diketiminato (Nacnac) ligand framework is reported. The hydride complex derived from the activation of H2 is shown to be a competent catalyst for the highly selective reduction of CO2 to a methanol derivative. To our knowledge, this process represents the first example of a reduction process of this type catalyzed by a molecular gallium complex. Ein ambiphiler Gruppe‐13‐Komplex wurde entwickelt, der zur kooperativen Aktivierung protischer, hydridischer und apolarer H‐X‐Bindungen befähigt ist. Der Hydridkomplex, der aus der Aktivierung von H2 entsteht, katalysiert die selektive Umwandlung von CO2 in ein Methanolderivat. Dies ist das erste Beispiel für solch eine durch einen molekularen Ga‐Komplex katalysierte Reduktion.
