scanning electron microscopy, and X‐ray photoelectron spectroscopy analysis. The heterogeneous nanocomposite has been used for one‐potsynthesis of various N‐heterocyclic compounds like pyrazoles, 1,2‐disubstituted benzimidazoles, 2‐arylbenzazoles, and 2,3‐dihydroquinazolin‐4(1H)‐ones under green reaction medium at room temperature. This novel method has several advantages, such as short reaction time, simple

This work represents the design and synthesis of efficient sulfonated cobalt ferrite solid acid catalyst. The synthesized solid acid green catalyst was characterized using various techniques viz. FT-IR, powder XRD, SEM, TEM and VSM. The obtained catalyst was used to synthesize biologically significant 2-substitutedbenzimidazole derivatives by condensation between o-phenylenediamine with various aromatic
