In organic chemistry, an imine (/ ɪˈmiːn / or / ˈɪmɪn /) is a functional group or organic compound containing a carbon – nitrogen double bond (C=N). The nitrogen atom can be attached to a hydrogen or an organic group (R).

亚胺 （英語： imine）是一种含 碳 － 氮 双键 的 官能团 或 有机化合物，通式为：R 1 R 2 C=NR 3，其中氮原子连接一个氢原子（H）或一个有机基团（R 3），碳原子则与另两个基团以单键连接。 [1][2][3] 亚胺可视为 醛 或 酮 中氧原子被NR基团（R可以是氢或有机基团）所取代得到的产物。 若NR 3 中的R 3 ＝H，化合物为一级亚胺；若R 3 ＝ 烃基，则化合物为二级亚胺。 亚胺是一种可参与多种反应的化合物，其应用在有机化学中随处可见。 [3] 若R 3 ＝OH，则称为： 肟；若R …

2022年3月7日 · Imines are the nitrogen analogues of aldehydes and ketones, containing a C=N bond instead of a C=O bond. They are formed through the addition of a primary amine to an aldehyde or ketone, kicking out a molecule of water (H 2 O) in the process.

write equations to describe the reactions that occur between aldehydes or ketones and primary or secondary amines. identify the product formed from the reaction of a given aldehyde or ketone with a given primary or secondary amine. identify the aldehyde or ketone, the amine, or both, required in the synthesis of a given imine or enamine.

Imines are compounds with a C=N double bond. Their general formula is R 2 C=NR. The nitrogen counterparts of aldehydes and ketones are imines, which have a C=N bond instead of a C=O link. They’re made when an aldehyde or ketone reacts with an amine to dehydrate it.

Imines and enamines can be hydrolyzed to aldehydes and ketones in acidic conditions: Remember, the reactions of aldehydes and ketones with alcohols and amines are all reversible and therefore, the products of these reactions – acetals, imines, and enamines can be converted back to carbonyl compounds if a large excess of water is used.

In organic chemistry, imine is a chemical compound whose structure contains a carbon-nitrogen double bond (C=N), with the nitrogen atom bonded to at least one other carbon atom. The carbon atom is also bonded to two other atoms or groups. A …

Imine and its by-products are vital intermediates in forming nitrogen heterocycles. They are used to synthesise dyes and coordination polymers. They are also known as Schiff Base and are synthesised during condensation reactions of aromatic amines with aldehyde and ketone.
