Benzimidazolium Dihydrogen Phosphate: A Novel Green Catalyst for the Preparation of Pyrano[2,3-𝑑]pyrimidines and Pyrano[3,2-𝑐]chromenes in Aqueous Media abstract

In this study, a novel benzimidazole-based Brönsted acidic ionic salt, benzimidazolium dihydrogen phosphate, was synthesized and characterized using Mass spectrometry, FT-IR and NMR spectroscopy, as well as ICP analysis. The salt demonstrated efficient catalytic properties and reusability in the production of pyrano[2,3-d]pyrimidine and pyrano[3,2-c]chromene derivatives. Noteworthy advantages of this approach include the minimal catalyst requirement, straightforward work-up process, brief reaction duration, high yields, and catalyst reusability for four consecutive uses without a significant decrease in efficiency.
