Abstract:
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.
