The Determination of N-Values for Some Amino-Acridines by Controlled Potential Coulometric Reduction

Abstract

The reduction of some aminoacridines has been investigated by controlled potential coulometry. The number of electrons involved in the first reduction stage has been determined by a graphical treatment of the current‐time values obtained using a divided electrolysis cell. With the exception of 5‐aminoacridine the results confirm the values obtained indirectly by Kaye5.

Electroanalysis and Coulometric Analysis

“…A sampling of some recent applications to the determination of the number of electrons involved in reactions include the following. Wilson, Butler, Ingle, and Taylor (295) found that the aminoacridines were reduced at a mercury cathode via a one-electron reduction, except for the 5-aminoacridine, whose reduction apparently involved a direct two-electron transfer. Butler and Martin (43) reported that crystal violet reduced in a one-electron reaction, but that the reduction of another triphenylmethane dye, brilliant green, was more complex.…”
