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

Abstract

Abstract.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.
