摘要：

In this article, simple impregnation technique was used to prepare copper oxide nanoparticles supported on nanomagnetite modified with a poly ionic liquid (Fe3O4@IL@CuO-np). The nanoparticles were used in an environmentally friendly method as a novel heterogeneous catalyst in the synthesis of 3,4-dihydropyrano[c]chromenes. The results showed that the novel catalyst was very inexpensive and efficient in the reaction and at the end of the reaction, it could easily be separated using an external magnet and reused for other reactions without significant loss of its catalytic activity.
