Sulfonation of the benzene ring of 3-(p-toluidino)-1-oxo-2-propene-2-sulfonic acid (III) (6.11×10^<-5>M) in 99.4% sulfuric acid at 25° was observed by following the UV spectral change of the solution. In a 9.51×10^<-1>M solution in 99.4% sulfuric acid, however, the bulk of III remained unchanged, and on dilution with 93.8% sulfuric acid, 6-methyl-quinoline (II) was formed. Sodium 4-(3-oxo-1-propenylamino) benzenesulfonate (V), sodium 4-(3-oxo-1-propenylamino)-3-methylbenzenesulfonate (VI) and sodium 2-(3-oxo-1-propenylamino)-5-methyl-benzenesulfonate (VII) were synthesized in connection with this investigation.
