Application
Sodium chlorite (NaClO2) can be used as an oxidizing agent for the conversion of:
It can also be used in combination with Br2 to synthesize 2-carboxyazetidin-2-ones from furanylazetidinones.
- Aldehydes to corresponding carboxylic acids under mild reaction conditions in the presence of scavengers such as sulfamic acid or resorcinol.
- Primary alcohols to carboxylic acids in the presence of 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) and NaOCl.
- Aliphatic and aromatic thiols to the corresponding disulfides.
- Aryl boronic acids to phenols via ipso-hydroxylation.
- Cyclic benzylic ethers and N-protected cyclic benzylic amines to benzolactones and benzolactams.
- Alkenes to epoxides using aldehydes as promoters.
- Alkenes and cycloalkenes to 1, 2 diols via osmium-catalyzed Sharpless asymmetric dihydroxylation.
It can also be used in combination with Br2 to synthesize 2-carboxyazetidin-2-ones from furanylazetidinones.
