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.
