Abstract EN
Triazine-based heterogeneous Pd/Cu-bimetallodendrimer Nanoparticle (Pd/Cu-BMDNP) has been synthesized by sequential loading method from palladium containing metallodendrimer (Pd-MD) which was prepared by the reaction of 2,4,6-Triamine-1,3,5-triazine (melamine) with substituted benzoyl chloride using (Ph3P)2PdCl2 in DMSO at 90 °C.
SEM and EDX of Pd/Cu-BMDNP showed the nanosized aggregated spherical surface morphology and the presence of Palladium and copper of the NP.
Also, the phase was detected as Face Centered Cubic (FCC) structure by XRD analysis.
In addition, the average particle size of Pd/Cu bimetallic catalyst was identified as 12–13 nm by TEM investigation.
Greater thermal stability of Pd/Cu-BMDNP than Pd-MD was detected from TG and DSC experiments.
The Pd-metallodendrimer has been also characterized by IR, 1H NMR, 13C NMR, SEM, EDX, Mass, TG and DSC techniques.
The simple recoverability, high reusability, low amount of catalyst loading, negligible amount of catalyst leaching of the heterogeneous Pd/Cu-BMDNP have made more effective catalyst than homogeneous Pd-metallodendrimer for the C–C cross-coupling reaction such as Heck, Glaser, Sonogashira and Suzuki-Miyaura in excellent yields.
