One pot of Sonogashira coupling and oxidation of alcohol reactions by magnetic nanocatalyst in an ideal environment

Abstract

Mainly in the new era, there is a need to accelerate chemical reactions, which is made possible by advanced nanocatalysts, whose magnetic nanocatalysts are highly efficient in controlling chemical reactions such as Sonogashira coupling and alcohol oxidation. Magnetic nanocatalysts are made of magnetite nanoparticles under the chemical co-precipitation method. Their structure was identified by analysis such as EDX (energy-dispersive X-ray) and XRD (X-ray diffraction). The Sonogashira carbon–carbon coupling reaction was performed twice consecutively, and the product efficiency was more than 97%. Oxidation of alcohols to produce aldehyde products is up to 99%. The structure of the magnetic nanocomposite was analyzed after several reuses, and the results showed that it was unchanged, and its performance, structure, and magnetic properties were fully preserved. The reaction conditions are at the lowest possible temperature, harmless solvents, and the highest efficiency percentage, which creates green conditions. The products obtained from the Sonogashira double coupling reaction have two triple bonds. Also, the products with the oxidation of alcohols, which are used as the main precursors in the chemical and medical industries for chemical and pharmaceutical production, are very important.
