Magnetically recoverable nonocatalyst Fe۳O۴@APTMS@dithiazone-Cu for the synthesis of ۴H-chromenes in an environmentally friendly manner

This study focused on synthesizing a core-shell structured heterogeneous nanocatalyst Fe۳O۴@APTMS@dithiazone-Cu, highlighting its key attributes such as stability, magnetic properities, separability, and recyclability. The catalyst’s presence in reactions enhances product yield, optimizes reaction time, and facilitates separation using a magnet for subsequent washing and reuse without compromising its catalytic efficiency. Moreover, it shows promise in facilitating green synthesis reactions like the production of ۴H-chromene compounds. The modification process involved treating Fe۳O۴ as a magnetic core with surfactant (SDS) and polyethylene glycol (PEG) coating, followed by functionalization with amino propyl tri methoxy silane (APTMS) and dithiazone, culminating in the incorporation of copper metal. Copper’s well-established catalytic properties make it a popular choice for environmental and industrial applications, further enhancing the overall performance of the nanocatalyst[۱,۲].
