Two hitherto unknown magnetic nanoparticles were prepared through the immobilization of Dysprosium (Dy) and Praseodymium (Pr) Complexes on the surface of CoFe 2 O 4 , using commercially available or easily accessible materials under green conditions. They were fully characterized, using, FT‐IR, SEM, EDX, ICP‐OES, XRD and TGA techniques. Photocatalytic activity of these nanocomposites were successfully examined in the high yielding synthesis of pyrano[2,3‐ d ]pyrimidines, via MCR, involving, barbituric acid, malononitrile and differently substituted benzaldehydes in the UV region (250 nm) at room temperature. The above‐mentioned photocatalysts showed excellent recoverability and reusability under the optimal reaction conditions.
