Super paramagnetic Fe3O4 nanoparticles have attracted worldwide attention and have been studied extensively due to their biological and technological applications. These magnetic nanoparticles are efficient supports which can facilitate isolation and recycling of expensive catalysts from the reaction media. Herein, Fe3O4 Nanoparticles were modified with N-[3-(triethoxysilyl)propyl]isonicotinamide (TPI) linker; then, H5PW10V2O40 and H6P2W18O62 were chemically anchored to the surface of the modified magnetite. The prepared catalysts were Characterized using several techniques such as UV-vis, XRD, SEM, TEM, and FTIR. Finally, the catalytic activity of the prepared catalysts was monitored for the synthesis of different substituted bis(indolyl)methanes and 1-amidoalkyl-2-naphthols. This protocol introduced efficient, ecofriendly, and highly recyclable catalysts for the solvent-free, one-pot, and multi-component synthesis of the mentioned synthetic routes.
