General description
Sodium perborate is widely employed as an oxidizing agent.
Application
Sodium perborate tetrahydrate may be employed for the following studies:
- Transformation of iodoarenes to (diacetoxyiodo)arenes.
- Oxidation of Π-deficient azines to afford N-oxides.
- Oxidation of sulphur containing heterocyclic compounds to afford S,S-dioxides.
- Microwave-assisted oxidative hydration of various aromatic and aliphatic nitriles.
- Various oxidation reactions of anilines and sulphides.
- As a catalyst for the transformation of 2′-hydroxychalcones to flavanones.
