Synthesis of tri and four substituted imidazoles derivatives using zinc oxid nanotubes modified by SiO2 as a powerful and reusable catalyst

In recent years, zinc oxid nanotubes have attracted much attention. The direct use of , zinc oxidnanotubes modified by SiO2 as recoverable catalysts for organic reactions is very rare. The catalystswere characterized by XRD. The average particle size of ZnO catalysts is 57 nm and there are highdensitydefects on nanotubes surfaces . A simple and efficient method for the imidazol derivativessynth...

ZrOCl2.8H2O@nano SiO2: a green and recyclable catalyst for the synthesis of benzimidazoles

ZrOCl2.8H2O@nano SiO2 has been synthesized for the first time via a simple procedure and characterized by SEM (scanning electron microscopy), FT-IR, and EDX (energy-dispersive X-ray) techniques. The efficiency of the prepared nanostructure has been explored for the synthesis of benzimidazoles via the condensation reaction of orthoesters and diamines at 60 °C under solvent-free conditions. The s...
