The novel organic–inorganic nanohybrid magnetic nanoparticles (HNPs@Py) were prepared by a simple method and characterized by FT-IR, XRD, FE-SEM, TGA, VSM, EDX, and MAP. The catalytic activity of this new (HNPs@Py) was studied for green synthesis of biscoumarin and 3,4-dihydropyrano[c]chromene derivatives. The short reaction time, high yields, simple workup, and easy separation of catalyst from the
