Diazonium salt of aromatic amines

WebAzo compounds are prepared by the reaction of diazonium salts with phenol under alkaline conditions. Primary aromatic amines react with nitrous acid at 0 o C to give a diazonium salt. Nitrous acid is in turn formed by the reaction of sodium nitrite with hydrochloric acid. The active reagent is nitrous anhydride or dinitrogen trioxide. WebThe diazotisation process involves the conversion of primary aromatic amines into diazonium ions. Because of its volatility, the diazonium salt is rarely stored and is used …
