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.
