Dinitrogen Tetroxide Impregnated Activated Charcoal (N2O4/Charcoal): Selective Oxidation of Sulfides to Sulfoxides and Disulfides to Thiosulfonates
Abstract Dinitrogen tetroxide was easily impregnated on activated charcoal to give a stable heterogeneous reagent (N 2 O 4 /charcoal). The chemoselective oxidation of sulfides to sulfoxides in the presence of different sensitive functional groups was achieved using this reagent in CH 2 Cl 2 at roo...
