A novel magnetically responsive nanocomposite, designated as [Fe3O4@SiO2@Si-pr-NMe2-et-NMe2-pr-Si@SiO2@Fe3O4][Cl][FeCl4] (FSRSFCF), was manufactured, and analyzed through techniques such as EDS, elemental mapping, FE-SEM, FT-IR, TG, and VSM. This nanocatalyst demonstrated high catalytic performance and magnetic recoverability in the green, solvent-free fabrication of 1-amidoalkyl-2-naphthols through the one-pot multi-component condensation of aryl aldehydes, 2-naphthol and acetamide. The reaction proceeded rapidly, delivering the target products with high yields ranging from 92% to 97% within 20 to 30 minutes.
