Draw the structure of the cross-link … WebAniline is an aromatic primary amine. It forms diazonium salt when treated with nitrous acid at 0-5 °C. Nitrous acid is generated in situ by the reaction of sodium nitrite with hydrochloric acid. The process is called diazotisation. The diazonium salt is coupled with an alkaline solution of β-naphthol to form an orange-red azo dye.
WebThe substitution of an aromatic amino group is possible via preparation of its diazonium salt and subsequent displacement with a nucleophile (Cl-, I-, CN-, RS-, HO-). Many Sandmeyer Reactions proceed under copper (I) catalysis, while the Sandmeyer-type reactions with thiols, water and potassium iodide don't require catalysis. Webin the reactions of the diazonium salts. We could find only one example of solvolysis by dioxane in which a diazonium salt of an azulene derivative was solvolysed by dioxane …
