✦ Synopsis

The cyclic voltammetric characteristics of two nitroamphetamine derivatives (2-nitro-4,jdimethoxyamphetamine and 2-nitro-4,5-methylenedioxyamphetamine) have been investigated in different media. In mixed media (aqueous buffer and DMF, dioxane, or acetonitrile) a reversible oneelectron reduction takes place to form a stable nitro radical anion. At more negative potential values, a further three-electron reduction occurs irreversibly to give the hydroxylamine derivative. Cyclic voltammetr?; (CV) has been employed to study the tendency of the nitro radical anions to undergo further chemical reactions. The subsequent chemical reaction corresponds to a second-order process, a dismutation reaction electrochemically initiated. Data about rate constants and half-life times in mixed media are reported.
