Grupo funcional amida.

酰胺是指含有和氮和与氮相连的酰基的一类化合物,官能团为RnE(O)xNR'2,其中R和R'指氢原子或有机基团,E常见的有碳、硫、磷等。有机化学中命名中未指明E原子时E为碳,可以看作羧酸与氨或胺缩合形成的化合物,是羧酸衍生物的一类,如甲酰胺,乙酰胺。当E为硫原子,x=2时为磺酰胺。本文以下所指为羰基-氮酰胺。

英语百科

Amide 酰胺

(重定向自Chapman rearrangement)
Structures of three kinds of amides: an organic amide, a sulfonamide, and a phosphoramide.
Amides possess a conjugated system spread over the O, C and N atoms, consisting of molecular orbitals occupied by delocalized electrons. One of the π molecular orbitals in formamide is shown above.

An amide (/ˈæmd/ or /ˈæmɪd/ or /ˈmd/), also known as an acid amide, is a compound with the functional group RnE(O)xNR′2 (R and R′ refer to H or organic groups). Most common are carboxamides (organic amides) (n = 1, E = C, x = 1), but many other important types of amides are known including phosphoramides (n = 2, E = P, x = 1 and many related formulas) and sulfonamides (E = S, x = 2). The term amide refers both to classes of compounds and to the functional group (RnE(O)xNR′2) within those compounds.
