Descrição

Descrição geral

Thionyl chloride is an inorganic acid chloride. It is mainly used as a chlorinating agent in organic synthesis for the production of organochlorine compounds.

Aplicação

Thionyl chloride can be used as a catalyst to synthesize:

• 4-(sulfinylamino)-1,2,4-triazole by reacting with 4-amino-1,2,4-triazole.
• Isothiazolopyrimidines from aminouracils via cyclization reaction.
• 1,2,6-triazine S-oxides by reacting with diimines via condensation reactions in the presence of pyridine.
• 2-oxo-1,3,2-dioxathianes by condensation reaction with alkane-1,3-diols.
• Cyclic sulfites by reacting with nitroglycols.
• Microporous organic polymers by aldol self-condensation reaction of di and multiacetyl building blocks.
