胺 àn （英語： amine）或 胺类[1]，是 氨 分子中的一个或多个 氢 原子被 烃基 取代 后形成的一类 有机化合物 [2][3]。 胺基 [註 1] （－NH 2 、－NHR、－NR 2）是胺的 官能团。 如果氮原子连着 羰基 （C=O），那么该化合物则称为 醯胺，其化学性质与胺并不相同。 在中国大陆（即便繁体），“胺”（读作：àn/ㄢˋ）字仅用作 化学名 後綴，即当氨基（－NR 2）是化合物“主要官能团”时，称为某某胺，如： 亚硝胺 等；当氨基（－NR 2）作为“次要官能团”时，则此官能团名称改 …

Amidines are organic compounds with the functional group RC (NR)NR 2, where the R groups can be the same or different. They are the imine derivatives of amides (RC (O)NR 2). The simplest amidine is formamidine, HC (=NH)NH 2. Examples of amidines include: A common route to primary amidines is the Pinner reaction.

In chemistry, amines (/ əˈmiːn, ˈæmiːn /, [1][2] UK also / ˈeɪmiːn / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.

An amine is a derivative of ammonia in which one, two, or all three hydrogen atoms are replaced by hydrocarbon groups. Amines are classified as primary, secondary, or tertiary by the number of hydrocarbon groups attached to the nitrogen atom. Amines are named by naming the alkyl groups attached to the nitrogen atom, followed by the suffix -amine.

2025年3月3日 · amine, any member of a family of nitrogen-containing organic compounds that is derived, either in principle or in practice, from ammonia (NH 3). Naturally occurring amines include the alkaloids , which are present in certain plants; the catecholamine neurotransmitters (i.e., dopamine , epinephrine, and norepinephrine ); and a local chemical ...

Amines are molecules that contain carbon-nitrogen bonds. The nitrogen atom in an amine has a lone pair of electrons and three bonds to other atoms, either carbon or hydrogen. Various nomenclatures are used to derive names for amines, but all involve the class-identifying suffix –ine as illustrated here for a few simple examples:

Amidines are nitrogen compounds that can act as bidentate ligands in coordination chemistry, often used to stabilize unusual scandium and yttrium compounds. You might find these chapters and articles relevant to this topic. Amidines are less useful than imidic esters and imidoyl chlorides for the preparation of hydrazonamides.
