The magnetic nanoparticle (Fe3O4) and catalytic antimony trichloride (SbCl3) were co-immobilized in the graphitic carbon nitride nanosheets (SbCl3@Fe3O4/g‑C3N4) using a straightforward solvent evaporation process. The designed catalysts showed excellent catalytic activity for the Groebke–Blackburn–Bienaymé multicomponent reaction for the preparation of substituted imidazo[1, 2-a]pyridines at room temperature. This convergent synthetic protocol enabled molecular diversity synthesis under appealingly mild conditions with operational simplicity in a selective, time, and cost‐effective manner. X-ray diffraction (XRD), infrared spectroscopies (FTIR), thermogravimetry (TG), Scanning electron microscopy (SEM), indicate the structural integrity of all components. The combination of environmentally benign reaction conditions, effortless composite recyclability offers magnetic carbon nitride economically viable for industrial processes.
