Application

1,2-Ethanedithiol can be used as a reactant to synthesize:
  • Aryl thiols via copper-catalyzed single-step reaction with aryl halides.
  • 1,3-Dithiolanes via Lewis acid-catalyzed chemoselective condensation with carbonyl compounds.
  • Polyalkylene sulfides via polycondensation with dibromides in the presence of NaH.
