Summary: In this study, a novel inorganic-organic hybrid catalyst based on Fe3O4 was successfully developed through four simple steps. The catalyst was converted into a porous nano magnetic catalyst by the presence of nickel and urea after constructing Fe3O4@SCH2CO2H. Various characterization techniques confirmed the identity of the prepared nanocatalyst. The catalyst was employed as a recoverable heterogeneous and nanoporous catalyst for the synthesis of spiro[indene-2,2'-naphthalene]-4'-carbonitrile derivatives, showing significant performance and reusability.
