General description

4-Chlorothiophenol undergoes oxidative coupling catalyzed by iron(III)-tetra phenyl prophyrin to form disulfides.

Application

4-Chlorothiophenol was used to modify poly(vinyl chloride) and to synthesize poly(vinyl chloride) with halogen groups.
Reactant involved in:
  • Oxidation to disulfides using cobalt-salen catalysts and air oxidizing agents
  • Thiourea-catalyzed sulfa-Michael addition to acryloyloxazolidinones
  • Pummerer-type cyclization
  • C-H Activation and C-S cross-coupling with heterocycles
  • Allylic sulfenylation with allylic carbonates
  • Lewis acid-catalyzed electrophilic ring-opening reactions of 2-aryl-3,4-dihydropyrans
