Room‐Temperature Aerobic Oxidation of Amines to Nitriles over Ruthenium Oxide Supported on CeO₂ Derived from MOFs

Abstract Heterogenous BPDC−RuO₂−CeO₂ catalyst derived from Ce−BPDC MOFs can successfully enable the oxidation of amines to nitriles under mild conditions (1 atm O₂, H₂O as a solvent, room temperature). The catalytic system has the good compatibility with benzylic and aliphatic amines. Lewis acid‐base pairs [Ru−O−Ce−Vö] formed by the combination of acidic oxygen vacancy and basic oxygen pair Ru−O−Ce on the surface of the catalyst is the key factor for the catalytic activity. The mechanical experiments indicate that amines adopt the step‐by‐step dehydrogenation process to nitriles in this transformation. Moreover, the catalyst could be recycled up to six times without the evident loss of catalytic activity and the change of morphology.
