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.

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.

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

Abiotic and biotic reductive dechlorination with chlorinated ethene dense non-aqueous-phase liquid (DNAPL) source zones can lead to significant fluxes of complete and incomplete transformation products. Accurate assessment of in situ rates of transformation and the potential for product sequestration requires

Highly functionalised benzofurans have been prepared from ortho-hydroxyphenones and 1,1-dichloroethylene. The key intermediate, a chloromethylene furan, smoothly rearranged into the corresponding benzofuran carbaldehyde under acidic conditions. Some mechanistic investigations have been performed and several biologically active benzofurans have been synthesised.

The presence of other chloroethenes influences aerobic metabolic biodegradation of cis-1,2-dichloroethene (cDCE). A new metabolically cDCE degrading enrichment culture was identified as also being capable of degrading vinyl chloride (VC), but not 1,1-dichloroethene (1,1DCE), trans-1,2-dichloroethene (tDCE), trichloroethene (TCE), or tetrachloroethene

Degradation of the lower chlorinated ethenes is crucial to the application of natural attenuation or in situ bioremediation on chlorinated ethene contaminated sites. Recently, within mixtures of several chloroethenes as they can occur in contaminated groundwater inhibiting effects on aerobic
