Dinitrogen tetroxide displays a unique feature in various oxidation processes. It can restrict a reaction to a single oxidation stage, when further oxidation still appears to be possible. Several workers have, therefore, used this reagent for the oxidation of alkyl, 1) aryl, 2) and alicyclic3) sulfides to the corresponding sulfoxides. In this note, we would like to report the oxidation of several disulfides with this reagent; this oxidation was carried out in a manner ...
