چکیده مقاله :
Catalyst is one of the most important principles of green chemistry which is widely used these days in chemical processes. On the other hand, chemists are always looking to design and fabricate catalysts that can be easily separated from the reaction mixture in addition to their high activity, in other words, the two most important features of a suitable catalyst are catalyst separation and catalyst activity [1-3]. All of these problems can be overcome by using magnetic nanocatalysts or changing the surface of magnetic nanoparticles and stabilizing catalyst species on magnetic substrates. Mn catalyst was used as a reusable catalyst for the green synthesis of tetrahydrobenzopyrans from the three-component condensation reaction of aryl aldehydes, dimedone, and malononitrile in refluxing ethanol. (Scheme 1).
