| Abstract: | Trisubstituted imidazoles have been synthesized in high yields in the presence of silica‐bonded S‐sulfonic acid as a catalyst. The reaction was carried out at 130°C under solvent‐free conditions. The reaction work‐up is simple and the catalyst is easily separated from the products by filtration. |
| Keywords: | silica‐bonded S‐sulfonic acid trisubstituted imidazole aldehyde catalyst solvent‐free |
