The Hydrolysis of Nitriles - Chemistry LibreTexts

WebWhen nitriles are hydrolysed you can think of them reacting with water in two stages - first to produce an amide, and then the ammonium salt of a carboxylic acid. For example, ethanenitrile would end up as ammonium ethanoate going via ethanamide. In practice, the reaction between nitriles and water would be so slow as to be completely negligible. WebDepending on reaction conditions, reactive intermediate imines can also undergo attack by amine products to afford secondary and tertiary amines: 2 R-C≡N + 4 H 2 → (R-CH 2) 2 NH + NH 3 3 R-C≡N + 6 H 2 → (R-CH 2) 3 N + 2 NH 3 Such reactions proceed via enamine intermediates.
