A Kinetic Study of Cyclodehydration of β-(p-Toluidino)-acrolein. I

抄録

The cyclodehydration of β-(p-toluidino)-acrolein (I) in sulfuric acid was studied kinetically in relation of that of 4-(p-toluidino)-3-penten-2-one (VII). Reversible sulfonation of I at α-position and cyclodehydration to 6-methylquinoline (II) proceeded in parallel. The difference in reactivity between β-arylaminoacrolein and 4-arylamino-3-penten-2-one was discussed.
