Abstract | dc.description.abstract | Four amphetamine derivatives bearing a methylenedioxy group at positions 3 and 4 of the
benzene ring and differing in their substitution at C(6) were studied by differential pulse voltammetry in
aqueous media. These experiments showed a single oxidation peak for the C(6)-H, -Br and -CI compounds,
while the C(6)-N02 analogue was not oxidized. The oxidation peak is interpreted as due to the removal
of one eleetron from the aromatic eleetrophore with formation of a radical cation stabilized by the dioxole
ring. The linear relationship between the peak current and the concentration of the derivatives is
appropriate for development of a quantitative method for their determination. pK' values were determined
using both eleetrochemical and spectrophotometric methods. | es_CL |
