Summary Various data connected with the Gomberg reaction are collected and discussed from the viewpoint that, although diaryl formation is explicable on a radical mechanism, the origin of the radicals is in the decomposition of diazonium ions rather than in that of the isomeric covalent diazo‐compounds. The difference in the reaction of diazonium salts with 2‐hydroxy‐1: 4‐naphthaquinone in acetic acid and alkaline media, respectively, is readily explained by modern resonance theory.
