Pseudo first-order rate constants for reactions of seven m- or p- phenyl-ring substituted 3,5-diphenyl 1,2,4-dithiazolium triodides with hydrazine in excess, in pyridine, were determined by a UV spectrophotometry. For these reactions, calculated some activation parameters, identified the reaction products, and investigated the effect of substituent on the reaction rate. These reactions were accelerated by electron-withdrawing substituents and obeyed the Hammett rule. From the observed kinetics, a reaction mechanism was proposed.
