The kinetics of the title reaction have been measured at various pS+ values.The results show the occurrence of general base catalysis and furnish information about substituent effects on the studied reaction.A reaction mechanism analogous to that proposed for the rearrangement of the arylhydrazones of 3-benzoyl-5-phenyl-1,2,4-oxadiazole is suggested.The reactivity of isoxazole derivatives is much lower than that of 1,2,4-oxadiazole derivatives.
