  • Oxidation of alcohols to ketones and aldehydes.
  • Oxidation hydroxylamine derivatives.    
  • Oxidation of arenes to quinones.

It can also be used:     
  • As a stoichiometric oxidant with chromium (IV) acetate for the oxidation of tertiary C−H bonds to tertiary alcohols.     
  • In combination with chromium oxide to oxidize primary alcohols to carboxylic acids; alkylbenzenes to benzoic acids; and cyclic benzyl ethers to the corresponding lactones.
