THE SYNTHESIS AND ACID-CATALYZED HYDROLYSIS OF N-(4-SUBSTITUTEDPHENYL)-O-BENZENEDISULFONIMIDES

Abstract

The acid catalyzed hydrolyses of some cyclic disulfonimides, N-(4-substitutedphenyl)-o-benzenedisulfonimides (1a-d) have been studied in concentrated aqueous acidic solutions. Analysis of the data by the Excess Acidity Method, activation parameters, substituent, and solvent deuterium isotope effect are all indicate hydrolysis by an A-1 mechanism in the studied range.
