Abstract:
Magnetically recoverable ZnFe2O4 nanoparticles was applied as an efficient catalyst in the synthesis of coumarin derivatives through the Knoevenagel condensation of different o-hydroxy benzaldehyde and 1,3- dicarbonyl compound. Some advantages of this sustainable protocol are high yields of coumarins, short reaction times, simple recovery of the nano ZnFe2O4 by external magnet and recyclable without important loss of their catalytic activity.
