Reaction of amine with hno2

WebIntro The “Sandmeyer Reaction” is a versatile method for replacing the amine group of a primary aromatic amine with a number of different substitutents. The amine is treated with “nitrous acid” (HNO2) under acidic conditions, which produces the diazonium ion. The WebIn every reaction, the amine is acidified with hydrochloric acid, adding a solution of sodium nitrite. The nitrite and the acid form nitrous acid, which reacts with the amine. …
