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.

Jul 27, 2015 · Researchers have developed a novel synthetic approach for converting imines to amines enantioselectively. The carbon atom of an imine is normally electron-poor and acts as an electrophile, reacting with a carbon nucleophile to form a …

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).

Mar 7, 2022 · 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.

May 3, 2023 · The main difference between imine and amine is that imine is an organic compound with a nitrogen atom double bonded to a carbon atom, where the carbon atom can be a part of an aldehyde or a ketone, while amine is an organic compound derived from ammonia by the replacement of one or more hydrogen atoms with organic groups.

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.

Feb 25, 2025 · The nucleophilic addition of amines involves reacting primary or secondary amines with carbonyl compounds like aldehydes or ketones. This forms imines (with primary amines) or enamines (with secondary amines) along with water as a byproduct.

Sep 30, 2024 · Imines are formed in a reversible, acid-catalyzed process (Figure 19.8.1 19.8. 1) 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.

Apr 7, 2024 · Imine is a functional group characterized by a carbon-nitrogen double bond, while amine involves a single bond between nitrogen and carbon or hydrogen. Imines are organic compounds featuring a carbon-nitrogen double bond often resulting from the condensation of a primary amine and an aldehyde.

Iron-catalyzed aerobic oxidative reactions of primary amines, secondary amines, benzylamines with anilines, and alcohols with amines in the presence of air as the economic and safe oxidant, provide several direct, practical, and greener approaches for the preparation of useful imines.
