Kinetic evidence for direct electron transfer between tris(4-bromophenyl)ammoniumyl and the acetate anion in acetonitrile solution

Abstract

The reaction between tris(4-bromophenyl)ammoniumyl, electrogenerated from the parent amine, and the acetate anion has been studied in acetonitrile solution using rotating disc voltammetry and shown to involve a direct electron transfer reaction, resulting in an EC′ mechanism, in contrast to a previously reported suggestion that acylation of the radical cation was the dominant reaction pathway under these conditions.
