Abstract

A moisture-stable diazine-based dendrimer assisted heterogeneous bimetallic Pd/Co nanoparticles (NPs) was synthesized which showed a simple, profitable and environmentally sustainable operation for the Sonogashira reactions under copper and solvent-free conditions with regained easily and recycled four times without substantial activity loss. Furthermore, the dendrimer was analyzed by IR, 1H NMR, 13C NMR, and elemental analysis whereas the Pd/Co bimetallic NPs was characterized by EDX, TGA & DSC, and XRD techniques.
