Abstract
The relative rates and Hammett correlations have been obtained for the title reaction in the temperature range 90-110 degrees C, yielding th e differential activation parameters (Delta Delta H(Y-H)double dagger and Delta Delta S(Y-H)double dagger). The two differential terms maint ain an isokinetic relation. The plot of Delta Delta S(Y-H)double dagge r versus sigma(+) gives a straight line with a negative slope.
