Reaction between amine and aldehyde
WebIn the case of amines, the nitrogen can react several times with the electrophile (alkyl halide), and in practice it is difficult to stop the reaction at any intermediate step (in the laboratory). Amines typically react with electrophiles to give poly-alkylated amines O, S, and N as leaving groups: WebReactions with ketones and aldehydes Primary amines react with carbonyl compounds to form imines (see section 21.4. ). Specifically, aldehydes become aldimines, and ketones become ketimines. In the case of …
