21.8: Condensation of Acids with Amines - Chemistry LibreTexts
The direct conversion of a carboxylic acid to an amide is difficult because amines are basic and tend to convert carboxylic acids to their highly unreactive carboxylates. In this reaction the carboxylic acid adds to the DCC molecule to form a good leaving group which can then be displaced by an amine during nucleophilic substitution.

The direct conversion of a carboxylic acid to an amide is difficult because amines are basic and tend to convert carboxylic acids to their highly unreactive carboxylates. In this reaction the carboxylic acid adds to the DCC molecule to form a good leaving group which can then be displaced by an amine during nucleophilic substitution.

2020年4月1日 · All possible chemical transformations between amine and carboxylic acid groups are mapped using an automated string-based combinatorics method, showing that the properties and functions of...
The Reaction Between Carboxylic Acids And Amines
2023年5月24日 · When a carboxylic acid and amine react, they form a compound called an amide. The reaction between a carboxylic acid and an amine is a nucleophilic acyl substitution reaction. The carboxylic acid donates its electronegative oxygen atom to the electron-deficient nitrogen atom of the amine, forming a new bond between the carbon and nitrogen atoms.
Exploring the combinatorial explosion of amine–acid reaction
2024年2月3日 · Herein we conduct a thorough exploration of amine–acid reaction space via systematic enumeration of reactions involving a simple amine–carboxylic acid pair. This approach to chemical...
DCC coupling – Amides from Amines and Carboxylic Acids
Without DCC, the amine deprotonates the carboxylic acid instead of a nucleophilic attack on the C=O. So, DCC has two main functions; 1) getting rid of the acidic proton, and 2) converting the oxygen into a good leaving group. In an identical reaction, EDC facilitates formation of amides from carboxylic acids:

2019年2月3日 · Amide bond formation is a different reaction that typically requires activation or harsher conditions (e.g. heating). It is a condensation that results in the release of water. All that is required is the presence of an amino group and a carboxylic acid. So aminoethane and ethanoic acid can be heated in solution to produce N-ethylacetamide.
Schmidt Reaction - Definition, Description, and Detailed …
The Schmidt Reaction can be employed to either get amides by reacting the azide with a ketone or to get an amine by reacting the azide with a carboxylic acid. The chemical reaction wherein amines can be produced from an azide and a carboxylic acid can be illustrated as follows:
Reactions of amines: Learn types, differences, reagents, uses
2023年5月15日 · Reaction of Amine with Carboxylic Acid. Amines react with carboxylic acids at an elevated temperature, undergoing condensation and forming an amide. The reaction cannot occur at room temperature as amines deprotonate carboxylic acids resulting in the formation of the highly unreactive carboxylate ion.
Formation of amides: one-pot condensation of carboxylic acids and ...
2017年9月15日 · The direct formation of amides by condensing non-activated carboxylic acids and amines is extremely attractive because of its low environmental impact. Using metal-based catalysis in direct amide preparation, as an alternative to coupling reagents, has …
