Application

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.

General description

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.

The effects of the molecular structure of thiazole-based polymers on the active layer morphologies and performances of electronic and photovoltaic devices were studied. Thus, thiazole-based conjugated polymers with a novel thiazole-vinylene-thiazole (TzVTz) structure were designed and synthesized. The TzVTz structure
