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.

“…Therefore, various methods have been reported for preparing this class of compounds . The most straightforward method to obtain the heterocycle involves the condensation of indoles with different carbonyl compounds (aldehydes or ketones), which was often promoted by homo‐ and heterogeneous catalysts such as acid catalysts, nano catalysts, supported catalysts, metal catalysts, ion exchange resin, and enzymes . Although these reported protocols have made some certain merits, many of them still have notable disadvantages such as harsh reaction conditions, long reaction times, limited substrate scope, using expensive Lewis acids and solvents, high catalyst loading and generation of large amounts of harmful wastes.…”

A facile and efficient protocol for the synthesis of C3‐substituted indole derivatives has been developed under mild condition. The iron‐containing ionic liquid, 1‐(2‐hydroxyethyl)‐1,4‐diazabicyclo[2.2.2] octanylium tetrachloroferrate ([Dabco‐C2OH][FeCl4]) as a recyclable catalyst has been successfully used in the synthesis of trisindolines, bis(3‐indolyl) methanes and β‐indolyl alcohols for the first time. The products of trisindolines and bis(3‐indolyl) methanes are easily separated and purified without chromatographic technique. The catalyst was recycled six times without significant activity loss.

Nanomagnetic Fe3O4@SiO2@ZnCl2 was used as a simple, cost-effective, and reusable heterogeneous catalyst for the synthesis of 2,6-diamino-4-arylpyridine-3,5-dicarbonitriles by a one-pot-three-component condensation reaction of malononitrile, ammonium acetate, and aldehydes under solvent-free conditions at 110 °C. Simple and mild reaction conditions, facile preparation of the catalyst, the use of a cheap catalyst and easy workup and isolation are notable features of this method. ABSTRAKNanomagnetik Fe3O4@SiO2@ZnCl2 digunakan sebagai katalis sederhana, hemat biaya, dan merupakan katalis heterogen yang dapat digunakan kembali untuk sintesis 2,6-diamino-4-arilpiridin-3,5-dikarbonitril melalui reaksi kondensasi tiga komponen one-pot antara malononitril, amonium asetat, dan aldehida dengan kondisi tanpa pelarut pada temperatur 110 °C. Kondisi reaksi yang sederhana dan ringan, persiapan katalis yang mudah, penggunaan katalis yang murah dan mudah dilakukan serta mudah diisolasi adalah aspek yang penting dari metode ini.
