A new heterogeneous catalyst for the solvent-free efficient oxidation of alcs. has been developed for a sustainable future with a green reaction technol. This work presents the additive and solvent-free catalytic conversions of primary and secondary alcs. as well as diols into their corresponding carbonyl compounds in moderate to excellent yields. The developed catalyst system is green as it oxidises alcs. under solvent-free conditions and uses simple atm. oxygen as the oxidising agent. We have exptl. proved that the alc. oxidation reaction proceeds through an aerobic oxidative pathway. The double perovskite oxide catalyst CaLaScRuO6+δ was prepared by the conventional solid-state method. The crystal structure was refined and characterized thoroughly to observe the effect of mixed valent Ru5+/Ru4+ ions in the oxygen-rich disordered structure. The conversion of diols into four-, five- and six-membered lactones can enhance the novelty of the present catalyst. The catalyst was found to be very selective for the alc. oxidation and resulted in the oxidised product without affecting the other functional groups present in the aromatic ring. A reaction mechanism has been proposed for understanding the possible role of mixed metals in heterogeneous catalysis. In the experiment, the researchers used many compounds, for example, (2,4-Dichlorophenyl)methanol (cas: 1777-82-8Formula: C7H6Cl2O).
(2,4-Dichlorophenyl)methanol (cas: 1777-82-8) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Formula: C7H6Cl2O
