WebSome alternative chromium reagents allow the selective preparation of aldehydes, such as PCC and PDC. Although the reagent is very acidic, the substrate in acetone is essentially titrated with the oxidant solution and only very acid-sensitive groups are incompatible. For example esters, even tert -butyl esters, remain unchanged. http://dept.harpercollege.edu/chemistry/chm/100/dgodambe/thedisk/qual/chromic.htm 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. smallwood parish council
