What is the mechanism of hydrolysis of nitriles?
- The hydrolysis of nitriles, which are organic molecules containing a cyano group, leads to carboxylic acid formation. These hydrolysis reactions can take place in either acidic or basic solutions. The mechanism for these reactions involves the formation of an amide followed by hydrolysis of the amide to the acid.
What is the reaction between nitriles and water?
- In reality, the reaction between nitriles and water doesn’t occur efficiently. We have to heat nitrile with either dilute acid or alkali for a reaction. The end product is similar in both cases, but the nature of the product may vary depending on the reaction condition.
How is nitrile reduced?
- In conventional organic reductions, nitrile is reduced by treatment with lithium aluminium hydrideto the amine. Reduction to the iminefollowed by hydrolysis to the aldehyde takes place in the Stephen aldehyde synthesis, which uses stannous chloridein acid.
How is nitrile heated?
- The nitrile is instead heated with either a dilute acid such as dilute hydrochloric acid, or with an alkali such as sodium hydroxide solution. The end result is similar in all the cases, but the exact nature of the final product varies depending on the conditions you use for the reaction. Acidic hydrolysis of nitriles.
