- Abstract
Herin, we demonstrate the synthesis and catalytic efficacy of Fe3O4@SiO2-Amine-DAB/Py-CuCl2 nanocomposite as a novel catalyst in synthesizing various 2,3,5-triaryl furans via oxidative cyclization of aryl ketones with styrenes and oxidation of sulfides to sulfoxides under eco-friendly conditions. Our catalytic system accommodates a broad substrate scope, encompassing aryl ketones, styrenes, and aryl sulfides with both withdrawing and donating groups on the ring, yielding target products with high yields. Additionally, the catalyst exhibits notable reusability, maintaining stable efficiency over seven runs, as confirmed by VSM, TEM, and ICP-OES analyses, which validate the structural integrity of Fe3O4@SiO2-Amine-DAB/Py-CuCl2 even after eight recovery cycles. The developed Fe3O4@SiO2-Amine-DAB/Py-CuCl2 nanocomposite catalyst, demonstrating its efficiency and reusability in synthesizing 2,3,5-triaryl furans and diaryl sulfoxides under environmentally friendly conditions, which contributes significantly to the advancement of green catalysis methodologies.
