Application of Functionalized Zn-Based Metal–Organic Frameworks (Zn-MOFs) with CuO in Heterocycle Synthesis via Azide–Alkyne Cycloaddition

Abstract

The main goal of this article is to discuss the expansion of click chemistry. A new catalyst composed of CuO nanoparticles embedded in Zn-MOF with the ligand 2,4,6tris(4-carboxyphenoxy)-1,3,5-triazine (H 3 L) is presented. The incorporation of CuO nanoparticles into the Zn-MOF structure led to desirable morphology and catalytic properties. The designed catalyst was evaluated for its catalytic role in the multicomponent reaction and copper-catalyzed azide−alkyne cycloaddition (CuAAC) for preparation of triazole rings with 80−91% yield. The catalyst demonstrated an appealing architecture and exhibited robustness, high efficiency, and environmental friendliness. Characterization of the catalyst was performed using various techniques, including Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopes (TEM), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), energy-dispersive X-ray spectroscopy (EDX), elemental mapping, and X-ray diffraction (XRD). The results suggest that this novel catalyst has the potential to be a valuable tool in the development of new synthetic approaches for a wide range of applications.

An immobilized Schiff base–Mn complex as a hybrid magnetic nanocatalyst for green synthesis of biologically active [4,3-d]pyrido[1,2-a]pyrimidin-6-ones

“…16–18 There have been numerous studies on the grafting and immobilization of metal complexes onto magnetic nanosized inorganic supports, demonstrating significant benefits in terms of enhanced catalytic activity and stability. 19–27 Supported metal complexes offer the advantage of easy separation from reaction mixtures using an external magnetic field, making them highly efficient and practical for catalytic applications. Furthermore, immobilizing metal complexes on inorganic supports can improve their catalytic performance by creating a stable environment for active sites, leading to improved selectivity and reusability.…”

Ti-based MOFs with acetic acid pendings as an efficient catalyst in the preparation of new spiropyrans with biological moieties

“…The main advantage of MOFs is their openable three-dimensional structure and designable, which allows for changing the volume and shape of the structure 7,8 . MOFs have a complex network structure that can be used in various fields such as storage and transport of gases, separation of materials, removal of pollutants from the environment, synthetic catalysis, and pharmaceuticals [9][10][11][12][13][14][15][16][17][18][19][20][21][22] . Due to the characteristics and structural diversity of MOFs, a lot of research has been conducted on the design…”
