Ammonolysis involves the cleavage of the carbon-halogen (C–X) bond in alkyl or benzyl halides by ammonia, leading to the substitution of the halogen with an amino (–NH₂) group. This method is conducted in a sealed tube at 373 K and allows for the synthesis of primary amines, which can further react to form secondary, tertiary amines, and quaternary ammonium salts.

Ammonolysis of alkyl halides involves the reaction of alkyl halides (R-X) with ammonia (NH₃) to produce amines. In this nucleophilic substitution reaction, ammonia replaces the halogen atom, resulting in the formation of primary amines (RNH₂). The process is significant in amine synthesis as it provides a straightforward and versatile route to primary amines. It is particularly useful for preparing amines with alkyl substituents since the reaction can be controlled to favor monoalkylation. Ammonolysis is widely employed in the synthesis of pharmaceuticals, agrochemicals, and various organic compounds, contributing to the versatility of amine production in organic chemistry.
