Facile synthesis of sulfonamide-functionalized melamine-based covalent organicframework incorporating bimetal oxide MnFe۲O۴ as an efficient catalyst for thepreparation of chromenes

Magnetic porous nanocomposites, such as MnFe۲O۴@COF functionalized with sulfonamide, aresignificant catalysts because of their extensive surface area, strong magnetism, and acidic properties,rendering them well-suited for organic reactions. They were employed in the production of chromenes fromaldehydes, ۴-hydroxycoumarin, and ۲-hydroxy naphthalene-۱,۴-dione. The magnetic nanocatalyst utilized inthis investigation exhibited the ability to be recovered after five cycles with minimal decline in activity
