- چکیده:
- چکیده انگلیسی: An efficient and eco-friendly method for the synthesis of benzimidazole derivatives through the one-pot cyclocondensation of the substituted aldehydes with o-phenylenediamines over zinc sulfide nanoparticles (nano-ZnS) in ethanol as solvent at 70 °C has been described. The present method has several advantages such as high yields, easy purification, mild reaction conditions, easy work-up and short reaction times. The nanoparticles are easily synthesized, cheap, air and moisture stable, and also heterogenic and green catalysts.

- چکیده:
- چکیده انگلیسی: 1-amidoalkyl-2-naphthols were prepared via one-pot multi-component reaction of 2-naphthol, aldehydes, and amides in the presence of nickel nanoparticles as a solid phase acidic catalyst, under solvent-free condition at 100 °C. The recent literature survey reveals that the nano nickel was used as heterogeneous catalyst and received noteworthy attention because of its inexpensive, non-toxic, low corrosion, waste minimization, easy transport and disposal of the catalyst. Short reaction times, high yields, and easy work-up are the advantages of this protocol.
