Reversible Closure and Cleavage of the Aziridinium Ring by Nucleophilic Substitution: Solvent Effects

The kinetics of ring opening of aziridinium ion by chloride and bromide ions in DMSO-water mixtures have been studied and compared with previously reported data on the reverse reaction.Activation parameters indicate that the C-Hal bond in the transition state of the reaction develops to a minor extent.This assumption is corroborated by the bromide:chloride ratio.Correlations with Kamlet-Taft solvent parameters showed that both opening and closure of the aziridinium ring are characterized by a similar nucleophilic solvation term.Taking this fact into account we assume a considerable degree of ring formation in the transition state of the reaction under study.
