P2O5-SiO2 (30% w/w) was found to be a useful catalyst for the synthesis of various 2-substituted aryl benzimidazoles under solvent-less and in solvent conditions from o-phenylenediamine and aldehydes. The products were directly recrystallized from methanol.
Ni2+ supported on hydroxyapatite-core@shell γ-Fe2O3 nanoparticles (γ-Fe2O3@HAp-Ni2+) was found to be a useful catalyst for the synthesis of benzimidazole derivatives from o-phenylenediamine and aldehydes under solvent and solvent-free conditions at 80 °C. This reaction affords the corresponding benzimidazole derivatives compared with the classical reactions this method consistently gives a high yield, easy magnetic separation, a […]
A green and efficient trifluoroacetate-bonded polyethylene graphene oxide composite was utilized in this research to prepare benzimidazoles with good to excellent yield under a solvent-free condition. The trifluoroacetate-bonded polyethylene graphene oxide composite was constructed by polyethylene/diethylenetriamine-functionalized graphene oxide composite bonded by 2-aminothiazole and CF3COOHmoieties. Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) analysis, field emission […]
