The introduction of two new imidazole-based bis-dicationic Brönsted acidic ionic liquids and comparison of their catalytic activity in the synthesis of barbituric acid derivatives
sulfate and bis-imidazolium perchlorate as two new bis-dicationic Brönsted acidic ionic liquids based on imidazole is reported. After characterization by FT-IR, mass and NMR spectroscopy and pH titration, the applicability of these reagents is studied in the promotion of the synthesis of 5-arylidene barbituricacids and pyrano[2,3-d] pyrimidinone derivatives. These methods possess some advantages such
