Imine - Wikipedia
网页Imines are common ligands in coordination chemistry. Particularly popular examples are found with Schiff base ligands derived from salicylaldehyde , the salen ligands . Metal-catalyzed reactions of imines proceed through such complexes.
Imines – Properties, Formation, Reactions, and Mechanisms
网页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.
10.6: Imines - Chemistry LibreTexts
网页2022年7月20日 · The electrophilic carbon atom of aldehydes and ketones can be the target of nucleophilic attack by amines as well as alcohols. 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.
Imine: Definition, Structure, Formation, and Mechanism
网页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 Schiff base is considered a subclass of imines. [1-4]
Imine - an overview | ScienceDirect Topics
网页Imines are compounds containing a carbon-nitrogen double bond > C N having substituents that can be the same or different at the carbon and nitrogen atoms. Imines typically result from the condensation reaction of a carbonyl compound and NH 3 or an amine.

网页2022年2月28日 · An imine is a compound that has the following general structural formula. R 1, R 2, and R 3 could be hydrogen atoms, alkyl groups, aryl groups, or any combination thereof. eg: If, in an imine molecule, the ligand on the nitrogen atom is an alkyl or aryl group, the imine is also called a Schiff’s base. eg:
19.8 Nucleophilic Addition of Amines: Imine and Enamine Formation
网页Imines are formed in a reversible, acid-catalyzed process (Figure 19.7) that begins with nucleophilic addition of the primary amine to the carbonyl group, followed by transfer of a proton from nitrogen to oxygen to yield a neutral amino alcohol, or carbinolamine.

网页Imines are pervasive in chemistry and biology, playing key roles both the in artificial Strecker synthesis of amino acids and their biosynthesis by L-glutamate dehydrogenase and by transamination. Imines are also involved in Stork’s α-alkylation and acylation of ketones by way of enamine intermediates. Oxidation and reduction in organic ...
