Jones reagent

Jones reagent (chromic acid in aqueous acetone solution)

Chromic acid,  H2CrO4 , is a strong acid in presence of acetone it act as good oxidising agent also know as Jones oxidising agents and is a reagent for oxidizing alcohols to ketones and carboxylic acids. 

In place of comic acid we can use Na2CrO4  (sodium chromate),  Na2Cr2O7  (sodium dichromate),  KCrO4  (potassium chromate),  K2Cr2O7  (potassium dichromate), and  CrO3  (chromium trioxide) are alike in one crucial manner: when they are combined with aqueous acid, each of them forms  H2CrO4 , and ultimately it is  H2CrO4  that is involved in the important chemistry.

Mechanism of Jone’s reagent

Application of Jones Reagent

Jone’s reagent

This is a sufficiently mild oxidising agent, so that it oxidises alcohols without oxidising or rearranging double bonds. MnO2 can oxidise 1° allylic or 1° benzylic alcohols selectively into aldehydes.

Example of Jones reagent (chromic acid in aqueous acetone solution)

CH3–CH=CH–CH2OH   CH3–CH=CH–CH=O
