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.
