The behaviour in alkaline media (water, water-dioxane, or water-dimethyl sulphoxide) of 2-phenylamino-1,3,4-oxadiazole (IH) has been studied, together with the title reaction.Chemical and kinetic evidence support the occurence of a ring conversion through an intermediate cyclic compound (IV-), followed by the formation of an open-chain anion (V-) that cyclizes fast to the triazole derivative (III-).
