Zn/Mo nanocomposite: An efficient and reusable catalyst for the synthesis of 4-H Pyran derivatives

Abstract

A efficient, novel, inexpensive Zn/Mo nanocomposite were prepared by Sol-Gel synthesis. These nanomaterials were characterized by Powder XRD, FT-IR, FE-SEM, EDS. Under mild circumstances, the resulting nanomaterial functioned as a heterogeneous catalyst in the quick and easy production of derivatives of tetrahydrobenzo[b]pyran. The ideal circumstances for synthesising tetrahydrobenzo[b]pyrans have been assessed. The highest yield (92%) was achieved under ethanol as solvent after 7 min at 80 °C with 0.03 g of Zn/Mo NCs present. The composite oxide catalyst was found to be very efficient for the reaction. Since the nanocatalyst can be recovered and recycled four times without significantly losing catalytic activity, it has been shown to be recyclable. Exemplary yields of every synthesized derivative were obtained. A unique recyclable nanocatalyst, high product yields, and safe reaction conditions are the protocol's notable features.
