This work aimed to synthesize a new heterogeneous catalyst (SO 3 H@Fe 3 O 4 magnetic nanoparticles) and the study of its catalytic behavior in synthesizing 3,3′‐(arylmethylene)‐bis‐(4‐hydroxycoumarin), bis‐(indolyl)‐methane, and 1,8‐dioxo‐octahydroxanthene derivatives. The characterization of obtained material has been performed by means of Fourier‐transform infrared spectroscopy, thermogravimetric analysis, X‐ray diffraction, vibrating sample magnetometer, and transmission electron microscopy. The main properties of this new methodology, compared to earlier ones, are the short times of reaction, mild reaction conditions, simple recovery of the catalyst by permanent magnetic field, excellent yields, and reusability of the catalyst for a minimum of six runs.
