The aim of this research is to synthesize a new sulfonic acid catalyst based on halloysite nanotubes (Hal-Py-SO3H) and characterize it as a solid acid nanocatalyst by various analytical techniques such as Fourier-Transformed Infrared spectroscopy (FTIR), Thermal gravimetric Analysis (TGA), X-ray Diffraction (XRD) analysis, Scanning Electron Microscopy (SEM), Vibrating Energy-Dispersive X-ray analysis (EDX), Transmission electron microscopy (TEM) and X-ray atomic mapping. Furthermore, this new catalyst was evaluated in synthesizing spiropyran derivatives via multicomponent reactions (MCRs) and Xanthen derivatives under environmentally sustainable conditions. The main advantages of this approach include green conditions, excellent yields, quick reaction rates, and ease of preparation. Additionally it was observed that the catalyst exhibited robust stability even after multiple recycling processes, indicating its potential for practical applications in sustainable chemical transformations.

Copper(II)/polyimide‐linked covalent organic frameworks under solvent‐free and microwave‐assisted conditions have been used in an efficient one‐pot protocol for the preparation of 2,4,5‐trisubstituted imidazoles via benzil, aromatic aldehydes and ammonium acetate. By applying solvent‐free conditions and microwave irradiation, three‐component condensation provides safe operations, low pollution, quick access to products, and an easy set‐up. As a result of its reusability, the catalyst can also be reutilized for many runs without missing any activity.

“…Among all of the transition metal catalysts used in carbon-carbon coupling reactions, cobalt has gained great attention due to its precious properties such as eco-friendly, low cost, nontoxicity, and good availability; therefore, many studies have shown the implementation of catalytic systems based on cobalt with the usage of various linkers in carbon-carbon coupling reactions [16,29,30]. 1 3 Silica-coated magnetic nanoparticles functionalized cobalt… Heterogeneous catalysts have played an important role in many catalyst systems because of their potential applications [31][32][33][34][35][36][37][38][39][40][41][42]. Among these, magnetite nanoparticles (MNPs) and especially Fe 3 O 4 showed that they possess valuable features such as easy separation and recycling by using an external magnetic field to avoid wasting catalyst after the end of the reaction [43][44][45][46][47][48].…”

In this study, the Co-based catalyst was prepared by cobalt immobilization on the surface of functionalized silica-coated magnetic NPs (Fe 3 O 4 @SiO 2 -CT-Co) as a magnetically core-shell nanocatalyst and characterized by FT-IR, TGA, XRD, VSM, SEM, TEM, EDX, EDX mapping, and ICP techniques and appraised in the Suzuki-Miyaura cross-coupling reaction under mild reaction conditions. The results displayed the superparamagnetic behavior of the Fe 3 O 4 NPs core encapsulated by SiO 2 shell, and the size of the particles was estimated about 30 nm. Compared with the previously reported catalysts, the engineered Fe 3 O 4 @SiO 2 -CT-Co catalyst provided perfect catalytic performance for the Suzuki-Miyaura cross-coupling reaction in water as a green solvent and it was much cheaper in the comparison with the traditional Pd-based catalysts. Importantly, the durability of magnetic nanocatalyst was studied and observed that it is stable under the reaction conditions and could be easily reused for at least six successive cycles without any significant decrease in its catalytic activity.
