The advancement of effective and sustainable synthetic approaches for organic heterocycles holds considerable importance, given their extensive applications in pharmaceuticals, agrochemicals, and materials science. In this context, imidazole derivatives have garnered significant interest due to their varied biological activities and structural adaptability. In recent years, Fe-NPs have surfaced as noteworthy green catalysts due to their minimal toxicity, extensive surface area, magnetic separability, and abundance in nature. This review article investigates the pivotal function of Fe-NPs in the synthesis of imidazole derivatives through two-component and multicomponent reactions conducted under mild and environmentally sustainable conditions. Moreover, the application of Fe-NPs significantly reduces the necessity for toxic reagents and solvents, thereby adhering to the tenets of green chemistry. This manuscript underscores the promise of Fe-NPs as a multifaceted and economically viable catalyst for the synthesis of biologically significant imidazole frameworks, presenting a compelling foundation for future developments in heterocyclic chemistry.
