Abstract
Abstract Spectroelectrochemical studies of aniline (C6H5NH2) oxidation in NH4F+2.3 HF at 1 V vs. Cu/CuF2 have shown that a short living intermediate is created before the formation of polyaniline. The intermediate is diamagnetic and on the basis of the experiments, we propose that it must be the nitrenium cation (C6H5NH+). The mechanism of polyaniline formation is rediscussed in view of the reaction of C6H5NH+ with aniline, which follows a pseudo-first-order kinetics and also results in the formation of a polymer with at least two non-equivalent structures.
