The N(α), N(β)-rearrangement of the two N-atoms which can be observed in solutions of <β-15N>-labelled p-substituted benzenediazonium ions follows dual substituent parameter treatments.The reaction yields a negative field and positive resonance reaction constant (ρF = -3.35, ρR = 2.47).The magnitude of these constants is, within experimental error, the same as the respective reaction constants for solvolytic dediazonation.The exchange of the diazonio group of 15N-labelled p-substituted benzenediazonium ion yields, however, field and resonance reaction constants for the forward and reverse steps in the complex mechanism of the exchange reaction.
