acid hydrolysis of nitriles mechanism
Which reagent is used for hydrolysis of nitrile?
Water is used along with the acid, to provide the reagent for the hydrolysis. Since nitriles can be prepared from alkyl halides + cyanide ion via an SN2 reaction, this hydrolysis step can be used to provide a two step synthesis sequence for making a carboxylic acid with one additional carbon.
How nitrile is converted into a carboxylic acid?
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. In the first step of acid-catalyzed hydrolysis, the protonation of the nitrogen activates the C-N triple bond for a nucleophilic attack of water:
What is nitrile hydrolysis?
Among the most useful reactions of nitriles is their hydrolysis to yield first an amide and then a carboxylic acid plus ammonia or an amine. The reaction occurs in either basic or acidic aqueous solution:
How does nitrile react with hydrochloric acid?
The nitrile is heated under reflux with dilute hydrochloric acid. Instead of getting an ammonium salt as you would do if the reaction only involved water, you produce the free carboxylic acid. For example, with ethanenitrile and hydrochloric acid you would get ethanoic acid and ammonium chloride.
