Coumarin derivatives are versatile heterocyclic compounds with significant applications in pharmaceutical chemistry, materials science, and photochemical systems. This review critically summarizes recent advances in the sustainable synthesis of coumarin derivatives using iron‑based magnetic nanocatalysts, with a focus on catalytic efficiency, recyclability, and environmental compatibility. Key Fe‑based systems, including Fe₃O₄ NPs, surface‑functionalized magnetic composites, and hybrid nanostructures, are discussed in relation to major transformations such as Knoevenagel and Pechmann condensations and multicomponent reactions. Particular attention is given to the impact of magnetic recoverability, high surface area, and tunable surface functionality on catalytic performance and green chemistry metrics. The influence of reaction parameters (solvent, temperature, catalyst loading, and functional group tolerance) on yield and selectivity is briefly assessed, and the advantages of magnetic nanocatalysts over conventional homogeneous and heterogeneous catalysts are outlined. Remaining challenges, including catalyst leaching, long‑term stability, and scalability, are highlighted, together with future directions for the rational design of advanced magnetic nanocatalysts for coumarin synthesis.
