Synthesis of fused Azo-linked 1, 2, 4-Triazole-3-Thione derivatives using Ag2S/RHA-MCM-41 nanocomposite



Magnetic nanoparticles have received much attention in synthesizing organic compounds due to their unique properties such as high contact surface, recyclability, and easy separation. In this study, Rice husk ash (RHA), an agriculture waste, was used as a silica source for MCM-41 synthesis. Ag2S/RHA-MCM-41 nanocomposite synthesized and characterized with FT-IR, SEM, and XRD. Prepared nanocomposite used for the synthesis of azo-linked 1, 2, 4-triazole-3-thione derivatives. Our study result showed that Ag2S/RHA-MCM-41 nanocomposite showed high activity in the synthesis of azo-linked 1, 2, 4-triazole-3-thione derivatives because of good yields and desirable reaction time. The structure of all compounds was determined by FTIR, 1H-NMR and 13C-NMR spectroscopy. In all reactions, the catalyst is easily removable and reusable, and its catalytic activity is maintained after five runs.
