Preparation and characterization of GO/KCC‐1/Ni(II) as an efficient catalyst for the green synthesis of some 1,8‐dioxodecahydroacridine derivatives

Abstract

ABSTRACTHerein, we successfully prepared a new heterogeneous catalyst for the synthesis of some 1,8‐dioxodecahydroacridine derivatives. The catalyst was prepared through the loading of KCC‐1 nanoparticles on graphene oxide (to prevent the agglomeration of KCC‐1 nanoparticles and extended the surface area), and the immobilization of Ni(II) on GO/KCC‐1 was done using a simple procedure. The structure of catalyst was characterized using X‐ray diffraction (XRD), field emission scanning electron microscope (FESEM), energy‐dispersive X‐ray (EDX), transmission electron microscopy (TEM), Fourier transform infrared (FTIR), elemental mapping, and thermogravimetric analysis (TGA) techniques. One‐pot pseudo‐four‐component reaction for the synthesis of 1,8‐dioxodecahydroacridines was performed under green conditions, and products were obtained in good to excellent yields. The structure of 1,8‐dioxodecahydroacridines was confirmed with FTIR, 1H NMR, and 13C NMR. Easy recovery and reusability of the catalyst, green conditions, short reaction times with high yield of products, and high‐efficient catalyst are some advantages of presented method.
