Abstract

An efficient, rapid, simple and scalable synthesis of 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles is shown by condensation reaction of benzil, aldehydes and ammonium acetate/aniline in the presence of deep eutectic solvents as eco-friendly ionic liquid catalysts under solvent-free conditions at 100 °C. This approach offers many advantages such as good yield, reduction of waste, short reaction time, easy isolation of products, facile purification and environmentally benign reaction conditions.
