Thermal [1, 3] benzoyl migration in 1-(α-benzoyloxyarylideneamino)-1,2,3-triazoles. Part II

1-(α-Benzoyloxyarylideneamino)-4, 5-dirnethyl-1,2,3-triazoles (V) were prepared by reacting the sodium salt of substituted 1-benzoylamino-4, 5-dimethyl-1,2,3-triazoles (IV) with benzoyl chloride at ?50°. The uncatalyzed thermal isomerization of isoimides V to the corresponding imides VI was studied kinetically and the reaction mechanism is discussed.
