Quinoxaline derivatives have been synthesized in a very short time with excellent yields by the condensation of 1,2‐diamines with aliphatic or aromatic 1,2‐dicarbonyl compounds or benzilmonoxime in the presence of silica sulfuric acid as a very inexpensive solid acid catalyst at room temperature. The recovery and reuse of the catalyst are also satisfactory.
