Praseodymium (III) anchored on the CoFe2O4 MNPs: An efficient heterogeneous magnetic nanocatalyst for one-pot, multi-component domino synthesis of polyhydroquinoline and 2,3-Dihydroquinazolin-4(1H)-one derivatives
In the present study, a facile technique to immobilize praseodymium (III) complex on the surface of magnetic nanoparticles was reported by available materials. The prepared samples were characterized by chemical and physical methods such as FT-IR, TGA, SEM, XRD and EDX techniques and were tested in the synthesis of polyhydroquinoline and 2,3-Dihydroquinazolin-4(1H)-one derivatives. It was observed that the yields of the reactions in the presence of the prepared nanocatalyst were good to excellent. More importantly, the use of a recoverable and novel magnetic nanocatalyst in these reactions is the outstanding feature of this protocol.
