Abstract:
The surface ofFe3O4 magnetic nanoparticles (MNPs) was modified by L-cysteine through condensation of COOH groups of
L-cysteine and OH groups on the surface of Fe3O4. The –SH group of preparedFe3O4@Cys MNPs oxidized to –SO3H group and Fe3O4@Cys–SO3H as an environmentally friendly magnetic nanoparticle was prepared. The MNPs were characterized by FT-IR, XRD, SEM and TEM studies. Then, the catalytic activity of the MNPs was evaluated as an effective and reusable catalyst for one-pot synthesis of 2H‐indazolo [1,2‐b] phthalazine‐triones derivatives. The results show that the catalytic activity of Fe3O4@Cys–SO3H was comparable to that of other reported heterogeneous and homogeneous catalysts
