Abstract
Trisubstituted imidazoles have been synthesized in high yields in the presence of silica sulfuric acid as an inexpensive solid acid catalyst under solvent-free classical heating conditions or using microwave irradiation. The silica sulfuric acid can be recovered for the subsequent reactions and reused without any appreciable loss of efficiency. © 2006 Elsevier B.V. All rights reserved.
