In this work, magnetic nanoparticle-supported sulfonic acid (γ-Fe2O3-SO3H) is used as an efficient catalyst for the synthesis of 2,4,5-trisubstituted imidazoles and 1,2,4,5-tetrasubstituted imidazoles in a short time (40-70 min for trisubstituted imidazoles and 30-40 min for tetrasubstituted imidazoles) and high-purity products were obtained (92-98% for trisubstituted imidazoles and 94-98% for tetrasubstituted imidazoles) in simple multicomponent reactions. Green and recyclable catalysts, eco-friendly and solvent-free conditions, high catalytic activity, shorter reaction time, easy recovery by an external magnet, high purity, and excellent yields are some features of these reactions.
