Hofmann rearrangement of benzamide in the presence of electrochemically generated hypochlorite

Abstract

Benzamide has been made to undergo Hofmann rearrangement, in the presence of hypochlorite (OCl^‐) generated in situ, by the electrolysis of sodium chloride solution using platinised titanium anode and graphite cathode. The product is not a pure primary amine, namely aniline; but a polymeric aniline derivative is produced. It has a free amino end; and/or a free amino end is generated during the process of diazotisation. The product has been diazotised and coupled with naphthols to give dyes. The nature of the dyes have been analysed by uv‐visible spectral studies. The dyes are slightly different from the dyes prepared from pure aniline.
