The use of bimetallic nanoparticles as catalysts in complex organic synthesis is rare, despite their widespread use in thermal C-1 chemistry and electrocatalysis. In this study, researchers demonstrate that intimate RuPt nanoalloys, supported on charcoal, can efficiently catalyze the synthesis of secondary and tertiary amines from various amino derivatives. The organic reactions include direct hydrogenation reactions and hydrogen-borrowing couplings, allowing for one-pot synthesis of desired amines from readily available materials.
The use of bimetallic nanoparticles as catalysts in complex organic synthesis is rare, despite the widespread use of these materials in thermal C-1 chemistry and electrocatalysis. Here we show that intimate RuPt nanoalloys, supported on charcoal, catalyze the synthesis of secondary and tertiary amines from a variety of amino derivatives, such as quinolines, isoquinolines, nitrobenzenes, oximes and nitriles, under mild reaction conditions. The organic reactions include not only direct hydrogenation reactions but also hydrogen-borrowing couplings in cascade, to access the desired amines in one-pot from readily available materials. The recyclable bimetallic solid catalyst is at least one order of magnitude more active than the monometallic counterparts in some cases, which illustrates the advantages of Ru-Pt co-operation during hydrogenation and hydrogen-borrowing reactions.
