WebThe reaction of aldehydes and ketones with ammonia or 1º-amines forms imine derivatives, also known as Schiff bases (compounds having a C=N function). Water is eliminated in the reaction, which is acid-catalyzed and reversible in the same sense as acetal formation. Web1° amines form the more stable imines. 2° amines form enamines. Consider the reaction of acetaldehyde with CH₃NHR, where R can be H or CH₃. The intermediate carbocation is CH₃-C⁺H—NRCH₃. R= H (1° amine): The …
Webreaction works well for substrates generated from aromatic aldehydes and anilines displaying o-, m- and p-substituents (Table€1, entries 1–7). Moreover, in one case the 3-aminoin- ... standard adducts from the amine–aldehyde–isocyanide 3CR were observed in some occasions [5-7] under our conditions presumably by attack of the unreacted ... 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:
