چکیده مقاله

In this research, the successful synthesis of spiro[acenaphthylene-1,9'-acridine] triones is described using 1,3-indandione, aniline and acenaphthoquinone in the presence of magnetic MnFe2O4@CS-Bu-SO3H NPs catalyst under ultrasonic irradiation in water. The catalyst was fully characterized by scanning electronic microscopy (SEM), vibrating sample magnetometer (VSM), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), energy dispersive X-ray (EDX), and Furrier transfer-infrared (FT-IR) spectroscopy. This method offers several advantages such as easy work-up, excellent yields, short reaction times, using of ultrasonic method, recoverability of the catalyst, and little catalyst loading.
