  7. Abstract:
  8. The magnetic MOF-based catalytic system has been reported here to be an efficient catalyst for synthesis of benzonitriles and diarylethers of aryl halides under optimal conditions. The MOF catalyst was built based on magnetic nanoparticles and UiO-66-NH2 which further modified with 2,4,6-trichloro-1,3,5-triazine and 5-phenyl tetrazole and the catalyst structure was confirmed by various techniques. Furthermore, the products’ yields were obtained in good to excellent for all reactions under mild conditions which result from superior activity of the synthesized heterogeneous catalyst containing palladium. Also, the magnetic property of the MOF-based catalyst makes it easy to separate from reaction mediums and reuse in the next runs. In summary, the presented article has been described preparation and application of the palladium MOF-based catalyst. The magnetic catalyst includes UiO-66-NH2 which has been modified with 2,4,6-trichloro-1,3,5-triazine and 5-phenyl tetrazole to support palladium nanoparticles. The shape and morphology of the modified UiO-66-NH2 was confirmed by FESEM and TEM analysis and they corresponded with pervious literatures. This catalytic system has shown very efficient activity for both syntheses of cyanoarenes and diaryl ethers in mild reaction conditions with good to excellent yields
