Reductive C‐N Bond Formation of Nitroarenes using Pd@rGO‐CuFe2O4 Magnetic Nanoparticles in Water towards the Synthesis of N‐Aryl Formamide and Azole Derivatives

Reductive C‐N bond generation strategies of nitroarenes to form N‐arylformamide and azole derivatives were developed under the influences of magnetically separable Pd@rGO‐CuFe2O4 nanoparticle‐catalyzed reaction conditions. These reactions proceed at a very low catalyst loading in H2O as the solvent, which leads to a higher percentage of yields (up to 96%) of the products. The catalyst is recovered from the reaction medium by using an external magnet and recycled for four consecutive reaction cycles with a less amounts of leaching.
