1 Results The oxidation of alcohols into the corresponding carbonyl compound is one of the most important functional group transformation in organic synthesis[1]. Traditionally,such transformations have been performed with stoichiometric inorganic oxidant or other high valent metal oxidant[2]. Despite a variety of systems for the catalytic oxidation of alcohols have been developed,there is ongoing interest in the search for new efficient and environmental friendly oxidation system.To the best of our knowledge,there is no literature report on the oxidation of alcohols using Oxone as oxidant in the catalytic mount of HBr in water under solar light.A typical procedure was carried out as follows: In an aqueous solution of alcohols (1 equiv.),Oxone (0.9 equiv.) and HBr (0.2 equiv.) was added.The mixture was stirred for 4h under illumination of sunlight.After completion of the reaction,the mixture was analyzed by GC/MS.Benzyl alcohol was readily converted into corresponding acid with 97% selectivity.Cyclohexanol and 4-methylbenzhydrol were completely transformed to the corresponding ketones with 100% selectivity. 1 Results The oxidation of alcohols into the corresponding carbonyl compound is one of the most important functional group transformation in organic synthesis [1].
