General description
Thionyl chloride is an inorganic acid chloride mainly used to prepare carboxylic acid chlorides from carboxylic acids.
Application
Thionyl chloride may be used in the following processes:
- To facilitate the synthesis of indenones from 3-hydroxyindanones via dehydroxylation.
- Surface modification of amorphous carbon nanotubes (α-CNTs) in stearic acid-dichloromethane solution.
- To functionalize silica gel for thioacetalization of aldehydes.
- Conversion of tert-butyl esters to acid chlorides.
- Conversion of aliphatic and aromatic sulfoxides to sulfides in the presence of triphenylphosphine.
- As an activator to generate ketenes in-situ for preparing 2-azetidinones.
