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.
