General description

Sodium periodate is an inorganic salt commonly used as an oxidizing agent for various organic substrates and a co-oxidant in a few other oxidation reactions. The oxidation of sodium periodate takes place in a water medium, but an organic co-solvent is used for organic substrates that are insoluble in water.

Application

Sodium periodate can be used as an oxidizing agent:
  • In the selective oxidation of sulfides to sulfoxides.
  • For the oxidative cleavage of a variety of 1,2-diols to generate aldehydes or ketones.
  • In the oxidation of diaryl, dialkyl, and aryl alkyl selenides to the respective selenoxides.
  • In the selective alkene epoxidation and alkane hydroxylation reactions.
  • In the selective oxidation of activated cellulose to obtain dialdehyde cellulose (DAC) by cleavage of the bond between C2 – C3 in the glucose unit.
  • It can also be used as an iodinating agent for the iodination of arenes and halo compounds.
