Jones oxidation - Wikipedia
Web7.10.2.1 In Aqueous Sulfuric Acid/Acetone (Jones Oxidation) Jones oxidation is a common protocol for the synthesis of carboxylic acids from primary alcohols in the presence of a wide variety of functional groups. The basis of Jones oxidation is similar to that of Cr (VI) salts in aqueous sulfuric acid where the reactive species is chromic acid. WebMany oxidising agents, like chromate, dichromate, iodine in N a O H etc. seem to work via ester formation and elimination. For example, chromic acid will react with the − O H of alcohol to form a chromate ester, and … WebThe chromium (V) acid promotes a two-electron oxidation of an alcohol and becomes Cr (III). Any residues of toxic Cr (V) and Cr (VI) compounds can be destroyed by the addition of an excess of 2-propanol once the intended reaction is complete. The formation of Cr (III) is indicated by a color change to green. phone app on ipad
