bio-template for Pd–Ag bimetallic nanoclusters and its formation is substantiated by standard analytical studies. The interfacial electron-transfer from the plasmonic metal Ag to Pd makes the newly developed heterogeneous-catalyst suitable for room temperature Suzuki–Miyaura coupling of nitrogen-rich heterocycles (74–93%) under visiblelight conditions. The enhanced catalytic activity, stability, and
AbstractA ligand‐free and heterogeneous palladium on carbon (Pd/C)‐catalyzed hetero‐Suzuki–Miyaura coupling reaction has been developed. The protocol enables the construction of both heterocyclic‐alicyclic and heterocyclic‐heterocyclic biaryl derivatives in good to excellent yields. Furthermore, Pd/C could be reused. The time‐course study clarified that palladium was leached into the reaction media as the reaction proceeded and then completely deposited on the carbon support.
