Chromic acid cro3
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.
