The thermodynamic parameters, Delta Delta H-# and Delta Delta S-#, were determined for the interception of an intermediate, with the structural characteristics of an aziridinium imide, by nucleophilic solvents during the reaction of 2-methyl-2-butene with N-phenyl-triazolinedione. The experimentally measured parameters were found to be in favor of an S(N)2-'like' transition state and showed strong dependence on the bulkiness of the incoming molecule of the nucleophile-solvent.
