Abstract

Fe3O4/g-C3N4/Alginate-Ag nanocomposite as a novel and effective nanocatalyst was successfully prepared. This nanocomposite was fully characterized using several techniques such as X‐ray diffraction (XRD), field emission scanning electron microscopy with energy dispersive spectroscopy (FESEM-EDS), transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FTIR). In addition, the catalytic activity of this novel and characterized nanocatalyst was investigated in the regioselective synthesis of 1,4-disubstituted 1,2,3-triazoles via click reaction and A3 and KA2 coupling reaction in aqueous media. The prepared nanocatalyst was simply recovered by using an external magnet and reused for several times with a slight loss of catalytic activity.

Highlights

Fe3O4/g-C3N4/Alginate-Ag nanocomposite as a novel and effective nanocatalyst was successfully prepared
In attempt to disclose the utility of C3N4 as a promising catalyst support for design and synthesis of heterogeneous catalysts[54,55,56,57], in this work, we claim the preparation and full characterization of F e3O4/g-C3N4/AlginateAg nanocomposite as an effective and novel nanocatalyst in the regioselective synthesis of 1,4-disubstituted -1,2,3-triazoles via Click[58,59,60] and A3 and KA261 coupling reactions under mild and environmentally benign conditions
F e3O4-g-C3N4-Alg-Ag is formed after decomposition of Ag NPs on the F e3O4-g-C3N4-Alg, and this spectrum shows the stability of Fe3O4-g-C3N4-Alg during synthesis of Ag NPs

Summary

Introduction

Fe3O4/g-C3N4/Alginate-Ag nanocomposite as a novel and effective nanocatalyst was successfully prepared. In attempt to disclose the utility of C3N4 as a promising catalyst support for design and synthesis of heterogeneous catalysts[54,55,56,57], in this work, we claim the preparation and full characterization of F e3O4/g-C3N4/AlginateAg nanocomposite as an effective and novel nanocatalyst in the regioselective synthesis of 1,4-disubstituted -1,2,3-triazoles via Click[58,59,60] and A3 and KA261 coupling reactions under mild and environmentally benign conditions. For the synthesis of triazole derivatives and A3 and KA2 coupling products, α-haloketones or alkyl halides, terminal alkynes and sodium azide, morpholine or piperidine and different aromatic aldehyde were used.
