Reaction of alcohols with ozone
WebThe reaction is operationally easy: a DMSO solution of the alcohol is treated with one of several electrophilic dehydrating reagents (E). The alcohol is oxidized; DMSO is reduced to dimethyl sulfide; and water is taken up by the electrophile. An amine base such as triethyl amine or pyridine is usually present in equimolar amount.

WebA common method for oxidizing secondary alcohols to ketones uses chromic acid (H 2 CrO 4) as the oxidizing agent. Chromic acid, also known as Jones reagent, is prepared by adding chromium trioxide (CrO 3) to aqueous sulfuric acid. The Jones oxidation also uses acetone as a co-solvent in the reaction to prevent over-oxidation of the organic product.
