摘要

Catalysis plays a crucial role in the chemical industry by enhancing reaction efficiency, reducing production costs, and minimizing environmental impact. With their unique properties, metal complexes can direct chemical reactions toward specific products, thereby improving selectivity and reducing waste. They also enable reactions to occur under milder conditions, thereby reducing energy consumption and associated costs. In this context, the synthesis and characterization of new complexes from various metal salts and pyrazole ligands are the main objectives of this work. The primary aim is to explore the potential of these compounds as catalysts for the oxidation of 2,6-dimethylphenol. The complexes were systematically synthesized and characterized using various spectroscopic and analytical methods, such as infrared (IR) with NMR, ultraviolet-visible (UV-Vis) absorption, X-ray diffraction (X-DR) analysis, and density functional theory (DFT) calculations. These techniques have allowed elucidating the molecular structures and electronic properties of the complexes. The catalytic activity of the complexes was evaluated through kinetic analysis, demonstrating their effectiveness as catalysts for the oxidation of 2,6-dimethylphenol (DMP). The results show that these new catalysts exhibit exceptional performance. The catalysts developed in this study offer significant potential for various industrial applications, providing more sustainable and economically viable solutions for oxidation processes. Furthermore, this research paves the way for optimizing existing processes and exploring new chemical reactions, thereby expanding the potential applications for these catalysts.
