Nickel-doped SnO₂ Nanoparticles: Preparation and Evaluation of Their Catalytic Activity in the Synthesis of 1-amido Alkyl-2-naphtholes

Abstract

Nickel-doped tin oxide nanoparticles (Ni-doped SnO₂) have been synthesized with the average size of 25 nm. The structural and compositional analysis of the prepared catalyst has been carried out by using XRD, XRF, TEM, and FT-IR. The prepared nanoparticles have been evaluated for their catalytic activity in the three-component reactions of aldehdyes, amides/urea and 2-naphthol at 100°C. The reaction results in the synthesis of a variety of 1-amidoalkyl-2-naphthol derivatives in high yields and catalyst can be recovered and recycled without a significant loss in the catalytic activity.
