Dinitrogen Tetroxide Impregnated Charcoal (N2O4/Charcoal): Selective Oxidation of Thiols to Disulfides or Thiosulfonates

Selective oxidation of thiols to disulfides (RSSR) was performed by using catalytic amounts of dinitrogen tetroxide/charcoal in chloroform at r.t. while the reaction of thiols with four molar equivalents of the reagent in dichloromethane afforded thiosulfonates (RSO 2 SR) with excellent yields.
