Abstract
The kinetic constants for the title reactions have been measured in benzene, at 25 °C, at various aniline concentrations. In spite of the low kB/k0 ratios, the reactions are inferred to be genuinely base-catalyzed. The susceptibility constants estimated for the various steps of the reaction mechanism(s) have allowed to make clear the limits of the so-called "element effect" criterion.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
