Abstract:
The magnetic MOF-based catalytic system has been reported here to be an efficient catalyst for synthesis of carbamates under optimal conditions. The robust MOF catalyst was built based on magnetic nanoparticles and HKUST-1 which further modified with thioacetamide and carbonization. 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 Cupper. 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 Cupper MOF-based catalyst. The shape and morphology of CoFe2O4@CNSCu was confirmed by FESEM, TEM and XRD analysis and they corresponded with pervious literatures.This catalytic system has shown very efficient activity for syntheses of carbamates in mild reaction conditions with good to excellent yields
