basic hydrolysis of nitriles mechanism
Can nitrile be hydrolyzed to carboxylic acids?
Nitriles can be hydrolyzed to carboxylic acids in acidic aqueous solutions, and to carboxylate salts with base-catalyzed hydrolysis: In both cases, the transformation consists of two main parts; conversion of the nitrile to an amide and hydrolysis of the amide to the corresponding carboxylic acid.
What happens when nitriles are hydrolysed?
This page looks at the hydrolysis of nitriles under either acidic or alkaline conditions to make carboxylic acids or their salts. When 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.
