Reduction of Nitro Compounds to Pragmatic Amines using Magnetic Separable and Reusable Stabilized Zn Substituted BiFeO3 Nanostructures

This study presents a green and efficient method utilizing BiFe0.9Zn0.1O3 (zinc-substituted bismuth ferrite) nanoparticles as a reusable catalyst for the chemoselective reduction of aromatic nitro compounds. Employing ethanol as the reaction medium at ambient temperature, the protocol facilitates the selective conversion of nitro groups to amino groups, even in the presence of other reducible functional groups such as halo, alkoxy, carbonyl, and cyanide. This approach consistently yields the desired products with exceptional selectivity and quantitative yields approaching 100%. Furthermore, the catalyst’s magnetic properties enable straightforward recovery and reuse, making this a sustainable and highly efficient strategy for industrial and synthetic applications.
