The kinetic data obtained in the study of the title reaction reveal unusual substituent effects.A logarithmic plot of reactivity data versus substituent constant (? and/or ?-) shows a 'zigzag' trend; it is suggested that this depends on a chang
Mononuclear Heterocyclic Rearrangements. Part 8. Substituent Effects on the Rate of Rearrangement of Some Arylhydrazones of 3-Benzoyl-5-phenyl-1,2,4-oxadiazole into 2-Aryl-4-benzoylamino-5-phenyl-1,2,3-triazoles, at pS+ 3.8-12.
