Reactions of Amines with Nitrous Acid Nitrous acid (HONO) is a weak acid and is prepared in situ by reaction of sodium nitrite with a strong aqueous acid Reaction of Primary Aliphatic Amines with Nitrous Acid Primary amines undergo diazotization with nitrous acid The unstable diazonium salts decompose to form carbocations
Reaction with HNO2 • Nitrous acid a weak acid is most commonly prepared by treating NaNO2 with aqueous H2SO4 or HCl • In its reactions with amines nitrous acid – participates in proton-transfer reactions – is a source of the nitrosyl cation NO+ a weak electrophile HNO2 H2OH3O + NO 2 + - pK + a = 3 37
