General description
Periodic acid, an oxoacid of iodine, is commonly used as a strong oxidizing agent. This inorganic acid is soluble in most solvents including water and ether.
Application
Periodic acid can be used in the following reactions:
It can also be used:
- 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.
- In the selective oxidation of sulfides to sulfoxides using FeCl3 as a catalyst.
