Magnetic nanoparticles are significant because of their wide range of applications as catalysts [1]. Also, deep eutectic solvents play a strong catalytic role in accelerating organic reactions including epoxidation, coupling reactions, and multicomponent reactions [2]. Multiparticle reactions are also common reactions for the synthesis of pyridone rings [3]. In this study, we used deep eutectic solvent-magnetic nanoparticles activated with ureadithiocarbamic acid as an efficient and potent recyclable catalyst for the synthesis of new component hybrid pyridones. This catalyst was fully characterized using several techniques such as FT-IR, NMR, EDS, elemental mapping, FE-SEM, TEM, TGA/DTG and VSM analysis. Then, the application of this catalyst in the synthesis of new hybrid pyridones with sulfonamide and triazole sections was performed. According to the results, the reactions were performed under mild green reaction conditions with high efficiency.
