General description

Sodium (meta)periodate is commonly used as an oxidizing agent in organic synthesis for the oxidation of various organic substrates. It can also be used as a co-oxidant with other oxidizing reagents such as osmium tetroxide and potassium permanganate. 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 (meta)periodate can be used as an oxidizing agent for the oxidation of:      
  • 1,2-diols to aldehydes or ketones via oxidative cleavage.       Sulfides to sulfoxides in the presence of phase transfer catalysts.      
  • Diaryl, dialkyl, and aryl alkyl selenides to the respective selenoxides.      
  • Phenols and their derivatives to corresponding quinones.
  • Acylphosphoranes to α,β-dicarbonyl compounds.

It can also be used in the:      
  • Selective alkene epoxidation and alkane hydroxylation,·
  • Oxidation of carbohydrates.      
  • Iodination of aromatic compounds.

Useful reagent for the oxidation of carbohydrates prior to labeling with biotin hydrazide

Features and Benefits

NaIO4 is a stable, selective, and cost-effective reagent that is capable of reacting under mild conditions.
