چکیده	Herein, we report Fe3O4@O2PO2(CH2)2NH3 +CF3CO2 − as a novel and reusable ionically tagged nanomagnetic catalyst. It was characterized by several techniques including Fourier transform infrared (FT-IR) spectroscopy, thermo gravimetric analysis/differential thermal analysis (TGA/DTA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM) and energy dispersive X-ray (EDX) analysis. The catalytic behaviour of the Fe3O4@O2PO2(CH2)2NH3 +CF3CO2 − was examined at the synthesis 2-amino-6-(2-oxo-2H-chromen-3-yl)-4-arylnicotinonitrile derivatives. Experimental data has approved that the final step of the plausible mechanism proceeded via a vinylogous anomeric based oxidation mechanism. Described catalys shows excellent potential of recycling and reusing at the described multicomponent reaction.
