WebJones reagent is a solution prepared by dissolving chromium trioxide in aqueous sulfuric acid.To effect a Jones oxidation, this acidic mixture is then added to an acetone solution of the substrate. Alternatively, potassium dichromate can be used in place of chromium trioxide. The oxidation is very rapid and quite exothermic.Yields are typically high. 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.
