Nano molten salts as eco-friendly and green catalysts play an important role in the chemical processes. Easy recovery and reusability of these catalysts have led to their extensive use in the synthesis of a wide range of compounds [1, 2]. Multicomponent reactions (MCRs) have become a paramount important route in organic chemistry because most of the atoms of starting materials contribute to the final product. Therefore, this type of reactions have been widely used in the synthesis of complex pharmaceutically active heterocyclic compounds, especially nitrogen-containing derivatives due to the biological activity [3]. In this work, we wish to reported a clean method for synthesis of good range of heterocyclic compounds at room temperature using phenanthroline-SO3H (5 mol%) as an efficient nano catalyst (Scheme 1).
