A simple, inexpensive, environmentally friendly, and efficient route for the synthesis of highly substituted imidazoles by the condensation of 1,2-dicarbonyl compounds, aldehydes, and ammonium acetate using 2,2,2-trifluoroethanol as a solvent is described. The solvent can be readily separated from reaction products and recovered in excellent purity for direct reuse.
