Abstract

Abstract The water-soluble carboxylic acid-functionalized aromatic disulfides, 3, 3′- dithiodibenzoic acid and 5, 5′-dithiodiisophthalic acid (5, 5′-dithiodi (1, 3- benzenedicarboxylic acid)) were prepared and their rates of periodate oxidation to the sulfonic acids were determined. The reaction is first order in each of the reactants which indicates that the slow step is the initial oxidative cleavage step. These aromatic disulfides ...
