Abstract

Abstract The reactions of phenylhydrazonopropanedinitriles with thiols are reversible and with increasing pH-values of aqueous solutions the equilibrium is shifted them to the side of the reactants. A mechanism of the decay of corresponding addition products was proposed and the kinetic description based on this mechanism is in good agreement with the obtained experimental data. From the viewpoint of the decay, the pH-dependent dissociation of the ...
