Magnetically retrievable nanocatalyst Fe₃O₄@CPTMO@dithizone-Ni for the fabrication of 4H-benzo[h]chromenes under green medium.

ABSTRACT: In the research, the core-shell procedure synthesized a novel magnetically separable heterogeneous nanocatalyst with high stability named Fe₃O₄@CPTMO@dithizone-Ni. In this method, Fe₃O₄ was modified as a magnetic core using surfactant (SDS) and polyethylene glycol (PEG) coating; after functionalizing the magnetic nanoparticles with 3-chloropropyl-tri-methoxysilane and dithizone, Ni metal was immobilized. The prepared catalyst was identified and specified utilizing diverse physicochemical techniques involving FT-IR, XRD, SEM, EMA, BET, ICP, EDS, TGA, Raman, and TEM. In the following, to vouch for the efficiency of the obtaining catalyst for the green synthesis of 4H-benzo[h]chromenes utilizing the three-component, one-pot condensation reaction of
