“…Reactions of organic monothio-, dithio-, monoseleno-, and selenothioacids of phosphorus, as well as their metal or ammonium salts with 0.5 equiv of halogens or sulfuryl chloride, are commonly used as methods of choice for the synthesis of organophosphorus disulfides [1][2][3][4][5][6][7][8][9] and diselenides [10][11][12][13]. Similarly, high yield formation of bis(thiophosphoryl)disulfides in the oxidation of phosphorodithioic acids and their salts with nitric acid, nitrogen oxides [14][15][16][17], hydrogen peroxides [6,7], and dimethyl sulfoxide (DMSO) [18] was also observed.…”
