Beschreibung

Allgemeine Beschreibung

1,2-Dichloroethylene, also known as acetylene dichloride, is a chlorinated aliphatic hydrocarbon that is commonly used as an extraction solvent and as a chemical intermediate for other chlorinated solvents and compounds.

Anwendung

1,2-Dichloroethylene, mixture of cis and trans can be used as a reactant to synthesize:

• Chloro-enynes from terminal alkynes via Sonogashira coupling.
• Trichloroethyl alkyl ketones by reacting with acyl chlorides via Friedel-Crafts reaction in the presence of aluminum chloride.
• (Ethenediyl)bis[thiazole] via Pd-catalyzed Stille-coupling reaction with 2-(tributylstannyl)thiazole.
