Abstract

Abstract Brønsted acidic ionic liquid, triphenyl (propyl-3-sulphonyl) phosphonium toluenesulfonate, has been used as an efficient and reusable catalyst for the one-pot synthesis of 2, 4, 5-trisubstituted and 1, 2, 4, 5-tetrasubstituted imidazoles under solvent-free conditions in excellent yields.
