Jones reagent

What is Jones reagent?

Jones reagent is generated by dissolving chromium trioxide CrO3 or potassium dichromate (K2Cr2O7 in concentrated sulfuric acid H2SO4, then diluted with a mixture of water and acetone to form an aqueous solution of chromic acid (H2CrO4).

Jones reagent is commonly employed for the oxidation of secondary alcohols, converting them into the corresponding ketone, for example, 2-propanol into acetone. Moreover, it is highly selective and efficient, and it is commonly used in organic synthesis.
