Description
Summary:Metal‐catalyzed selective activation of C–H bonds is very important for the construction of a variety of biologically active molecules. Supported alloy nanoparticles are of great interest in various catalytic applications due to the synergistic effects between different metals. Here, well‐dispersed CuPd alloy nanoparticles supported on reduced graphene oxide (rGO) were synthesized and found to be highly efficient and recyclable catalyst for the chelation‐assisted C (sp2)–H bond activation. Aromatic ketones or esters were synthesized via the cross‐dehydrogenative coupling (CDC) reaction between 2‐arylpyridines and alcohols or acids. Moreover, the catalyst was recovered and used for five times without significantly losing activity. Monodisperse CuPd alloy nanoparticles supported on reduced graphene oxide (rGO) were synthesized and found to be highly efficient and recyclable catalyst for the chelation‐assisted C (sp2)–H bond activation.
