Succinimidium Perchlorate as a Novel and Efficient Brönsted Acidic Ionic Liquid Promoter for the Synthesis of 5-arylidene Barbituric Acid and pyrano[2,3-d] Pyrimidinone Derivatives

Introduction: In this article, succinimidinium perchlorate as a new acidic ionic liquid catalyst was prepared and used to synthesize 5-arylidene barbituric acid and pyrano[2,3- d]pyrimidinone derivatives. Method: These two derivatives of barbituric acid have a variety of useful properties. Result: The advantages of this reagent were high yields, high efficiency, short reaction times, easy performance, easy work-up and reusability. Conclusion: Succinimidinium perchlorate, which was made for the first time in this project, was identified with different methods, including FT-IR, 1H NMR, 13C NMR and mass spectroscopic techniques derivatives of benzimidazole, which are shown in this review as a powerful scaffold.
