Ultrasonic activated efficient synthesis of chromenes using amino-silane modified Fe3O4 nanoparticles: A versatile integration of high catalytic activity and facile recovery
چکیده انگلیسی


• Synthesis, characterization and catalytic efficiency of amino-silane modified Fe3O4 nanoparticles.
• Catalytic activity for synthesis of 2-amino-4H-chromene derivatives.
• Recycle study of the catalyst.

An efficient synthesis of 2-amino-4H-chromenes is achieved by one pot three component coupling reaction of aldehyde, malononitrile, and resorcinol using amino-silane modified Fe3O4 nanoparticles (MNPs-NH2) heterogeneous nanocatalyst under sonic condition. The attractive advantages of the present process are mild reaction conditions, short reaction times, easy isolation of products, good yields and simple operational procedures. Combination of the advantages of ultrasonic irradiation and magnetic nanoparticles provides important methodology to carry out catalytic transformations.
