alkaline hydrolysis mechanism
How is amide formed in alkaline hydrolysis?
The mechanism involves protonation of the amide on oxygen followed by attack of water on the carbonyl carbon. The tetrahedral intermediate formed dissociates ultimately to the carboxylic acid and the ammonium salt: In alkaline hydrolysis the amide is heated with boiling aqueous sodium or potassium hydroxide.
What is alkaline hydrolysis?
Alkaline hydrolysis usually refers to types of nucleophilic substitution reactions in which the attacking nucleophile is a hydroxide ion. The best known type is saponification: cleaving esters into carboxylate salts and alcohols.
What is an example of acid-base-catalysed hydrolysis?
Acid–base-catalysed hydrolyses are very common; one example is the hydrolysis of amides or esters. Their hydrolysis occurs when the nucleophile (a nucleus-seeking agent, e.g., water or hydroxyl ion) attacks the carbon of the carbonyl group of the ester or amide.
