18.8: The Reactions of Aldehydes and Ketones with Amines and Amine …
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 …
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 …
19.8 Nucleophilic Addition of Amines: Imine and Enamine Formation
An aldehyde or ketone reacts with a primary amine, RNH 2, to yield an imine, in which the carbonyl oxygen atom has been replaced by the =N–R group of the amine. Reaction of the …
Imines from Aldehydes and Ketones with Primary Amines - Chemistry Steps
Aldehydes and ketones react with primary amines, in mildly acidic conditions, forming an imine (a Schiff base). The reaction with secondary amines produces enamines: Just like the reaction …
Hydrolysis of imines to give ketones (or aldehydes)
Description: Treatment of imines with water leads to their hydrolysis back to aldehydes (or ketones) and an amine. Notes: The reaction is assisted through the use of an acid catalyst. …
• The carbonyl reactant can be an aldehyde or a ketone • The amine reactant must have at least one hydrogen, as shown above; but R 2 and/or R 3 can be either a carbon or a hydrogen.
24.7 Reactions of Amines - Organic Chemistry - OpenStax
Primary and secondary (but not tertiary) amines can also be acylated by nucleophilic acyl substitution reaction with an acid chloride or an acid anhydride to yield an amide (Section 21.4 …
