A melamine-based dendrimer was used to prepare a new class of heterogeneous Pd/Cu bimetallic nanoparticles (NPs). The physicochemical characteristics of Pd/Cu bimetallic NPS were studied with the aid of SEM, EDX, XRD, TG& DSC techniques. Leafs shape surface morphology and the presence of required palladium and copper ion were observed from SEM and EDX analysis respectively while TG& DSC showed good thermal stability, as well as XRD, revealed nano-shape FCC structure. The recycling ability of the catalyst was examined for five successive runs without any noteworthy loss of activity. The synthesized Pd/Cu bimetallic NPS exhibited high catalytic activity in the synthesis of ynone in which synthetic route was phosphine ligand-free.
