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

Abstract

Herein, 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, 1 H NMR, and 13 C 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.

Efficiency and development of guanidine chelate catalysts for rapid and green synthesis of 7‐amino‐4,5‐dihydro‐tetrazolo[1,5‐a]pyrimidine‐6‐carbonitrile derivatives supported by density functional theory (DFT) studies

“…MCR may be conducted in some techniques, like transition metal, non‐metal, and nano‐particle catalyzed MCR 5,6 . Several types of heterocyclic structures have been advanced using metal‐catalyzed MCR impacts, which provided straightforward workup procedures as well as high products of obtained products 7–9 . Transition metal chelates were widely used as catalysts in MCRs because of their great catalytic performance as well as adaptability.…”

“…This permits them to initiate as well as chelate multiple starting materials instantaneously, advancing to the construction of several organic compounds through high competence as well as selectivity 11 . Tested metal‐based catalysts are toxicologically low, as well as extremely complex steady; see the conditions toward the green chemistry that applied in catalytic behavior 9 . Metal catalysts have ligands that function as N 2 donors to stabilize them by a good candidate.…”

Green pathway to the synthesis of some spirooxindole derivatives using NGO/PMA as a new and effective solid acid catalyst

“…[2][3][4][5][6] In recent years, the application of GO-based composites as green catalysts in organic synthesis has attracted more attention. [7][8][9] Oxygen-based groups, defects, and the unique two-dimensional (2D) structure of GO are the main factors in the chemically attachment of catalytically active materials on GO surfaces. [10][11][12][13][14][15][16] Recently, some efforts have been reported on the doping of elements between the carbon networks of GO.…”

“…[10][11][12][13][14][15][16] Recently, some efforts have been reported on the doping of elements between the carbon networks of GO. Doping of hetero atoms through the GO networks is an effective strategy for enabling GO sheets to be used in nano-devices [17][18][19] and catalysts [7][8][9]20 due to its superior physical properties and remarkable structure. Till now, several methodologies have been suggested for the synthesis of NGO, such as chemical vapor deposition (CVD), 21 arc-discharge method, 22 and hydrothermal method.…”

“…GO has some fascinating properties such as high sheet resistance, dynamic electronic properties due to the existence of sp3‐hybridized carbons bonded to oxygen, high surface area, semiconductor behavior, and high potential in energy storage 2–6 . In recent years, the application of GO‐based composites as green catalysts in organic synthesis has attracted more attention 7–9 . Oxygen‐based groups, defects, and the unique two‐dimensional (2D) structure of GO are the main factors in the chemically attachment of catalytically active materials on GO surfaces 10–16 …”
