摘要：

Trisubstituted imidazoles have been synthesized in high yields in the presence of silica sulfuric acid as a catalyst. The reaction is carried out in water, a very green solvent, under reflux conditions. The reaction work-up is simple and the catalyst is easily separated from the products by filtration.
