Nano CuFe_2O_4: A reusable magnetic catalyst for the synthesis of 2-amino-5,10-dioxo-4-styryl-5,10-dihydro-4H-benzogchromene-3-carbonitrile via a one-pot multicomponent reaction

摘要

Catalytic application of copper ferrite nanoparticles in benzo[g]chromene-3-carbonitril synthesis via one-pot, three-component reaction has been explored. The product was obtained in a high yield (60-90%) in the varied conditions. The catalyst can be recovered and reused for five consecutive running without significant decrease in catalytic activity.
