A Magnetically Recoverable and Highly Effectual Fe۳O۴ Encapsulated MWCNTs Nano-Composite for Synthesis of ۱,۸-Dioxo-octahydroxanthene Derivatives

۱,۸-Dioxooctahydroxanthene derivatives were synthesized from ۵,۵-dimethyl-۱,۳-cyclohexanedione and substituted aromatic aldehydes in attendance of Fe۳O۴@OMWCNT aseco-friendly and recyclable nano-catalyst. The heterogeneous and magnetically separable catalyst was prepared as per procedure and characterized with help of analytical tools. After successful characterization of catalyst, it was used for present transformation, which reported ۹۰-۹۶% yield of isolated product. Key advantages of this method are magnetically separable and reusable catalyst, improved yield, short time, less expensive, and easy handling of reaction procedure.
