MCM-41-nPr-NHSO3H was used as an efficient heterogeneous catalyst for the one-pot synthesis of imidazoles derivatives under solvent free conditions with good to excellent yields. The present methodology offers several advantages such as less waste, simplicity of procedure, short reaction time, easy and quick isolation of the products.
