Abstract:

Selective oxidation of alcohols to their aldehydes and ketones is an important synthetic conversion both in the organic synthesis and industrial chemistry. Owing to the corresponding carbonyl compounds are exceedingly valuable intermediates in various industries. The collection of reagents that have been developed to accomplish this transformation is reflects its significance. However, noncatalytic oxidation of alcohols using stoichiometric quantities of oxidants such as chromium, ruthenium, manganese oxides, permanganate, dichromate, hypochlorite, Swern and Dess-Martin reagents are relatively expensive, highly toxic, timeconsuming and pollute the environment. Hence, with increasing environmental concerns and in order to save time and money, enormous efforts have been assigned to the design of greener catalytic systems that employ H2O2 as a clean, cheap, eco-friendly co-catalyst oxidant. In this study, for the first time, we designed a novel heterogeneous catalyst (labeled as wo4 2-@IL-CQDs) for selective oxidation of alcohols to aldehydes and ketones. In the resulting catalyst, ILs-modified carbon quantum dots act as a metal-free support for the immobilization of Tungstate ions (wo4 =) which is necessary for oxidation. The above catalyst high activity and selectivity in alcohols oxidation in present H2O2 as oxidant.
