Mononuclear Rearrangement of the Z‑Phenylhydrazones of Some 3‑Acyl-1,2,4-oxadiazoles: Effect of Substituents on the Nucleophilic Character of the >CN–NH–C6 H5 Chain and on the Charge Density of N‑2 of the 1,2,4-Oxadiazole Ring (Electrophilic Counterpart)

The reaction rates for the mononuclear rearrangement of the Z-phenylhydrazones of 3-acyl-1,2,4-oxadiazoles 3a–c into the relevant 2-phenyl-2H-1,2,3-triazoles (4a–c) have been measured in dioxane/water at different temperatures in a large range of proton concentrations. The occurrence of two differen...
