Präzisierung der Konstitution der Sulfonierungsprodukte von o-Toluidin
Sulfonation of o-toluidine (1) in oleum yields only 2-amino- toluene-4-sulfonic acid (4), while the isomeric 2-aminotoluene- 5-sulfonic acid (2) can be prepared solely by baking the acid sulfate salt of 1. Further sulfonation of 4 afforded 2-amino- toluene-4,5-disulfonic acid (6) whose structure wa...
