Imine - Wikipedia
The general structure of an imine. 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).
Imine: Definition, Structure, Formation, and Mechanism
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.
Imines – Properties, Formation, Reactions, and Mechanisms
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.
21.4: Imine formation - Chemistry LibreTexts
The 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.

identify the aldehyde or ketone, the amine, or both, required in the synthesis of a given imine or enamine. write the detailed mechanism for the reaction of an aldehyde or ketone with a primary amine. write the detailed mechanism for the reaction …
19.8 Nucleophilic Addition of Amines: Imine and Enamine Formation
Mechanism of imine formation by reaction of an aldehyde or ketone with a primary amine. The key step is the initial nucleophilic addition to yield a carbinolamine intermediate, which then loses water to give the imine.
19.8: Nucleophilic Addition of Amines - Imine and Enamine …
Imine formation is a reversible process that starts with the nucleophilic addition of a primary amine to the carbonyl group of an aldehyde or ketone. Next, a proton transfer forms a neutral amino alcohol called a carbinolamine.
10.6: Imines - Chemistry LibreTexts
2022年7月20日 · The end result of attack by an amine nucleophile is a functional group in which the C=O double bond is replaced by a C=N double bond, and is known as an imine. (An equivalent term is 'Schiff base', but we will use 'imine' throughout this book).
Imine: Preparation, Properties, Reactions - Science Info
2023年11月11日 · The primary difference between imine and enamine is that imine has a C=N bond, whereas enamine has a C-N bond. Imines are produced when a primary amine (or ammonia) interacts with a carbonyl-containing acid (H+, H3O+).
Imine - Formation, Functional Group, Reduction & Imine vs …
An imine is a functional group or chemical compound containing a carbon–nitrogen double bond. Imines are chemical molecules with a double bond between carbon and nitrogen (C=N). They are made by substituting the oxygen atom in aldehydes and ketones with the (N-R) group.
