Dennis, W. H. Jr.; Rosenblatt, D. H.; Simcox, J. R. published an article in 1974, the title of the article was Synthesis of nitrotoluenesulfonic acids by oxidative cleavage of disulfides.Reference of 2-Chloro-4-methyl-1-nitrobenzene And the article contains the following content:
Oxidation of the disulfides [I and II (r = 4-Me, 5-Me)] gave 85% 5,4,2-Me(O2N)2C6H2SO3H, 11% 4,2-Me(O2N)C6H3SO3K, and 20% 5,2-Me(O2N)C6H3SO3K. I and II were prepared (52-95%) by the reaction of 5,2,4-Cl(O2N)2C6H2Me and x,yCl(O2N)C6H3Me(x = 4, y = 3; x = 3, y = 4), resp. with Na2S2. The experimental process involved the reaction of 2-Chloro-4-methyl-1-nitrobenzene(cas: 38939-88-7).Reference of 2-Chloro-4-methyl-1-nitrobenzene
The Article related to toluenesulfonic acid nitro, oxidative cleavage disulfide, Noncondensed Aromatic Compounds: Sulfenic, Sulfinic, and Sulfonic Acids and Derivatives and other aspects.Reference of 2-Chloro-4-methyl-1-nitrobenzene
