What is formed when a carboxylic acid and an amine combine?
Amines and carboxylic acids can combine in a condensation reaction to form amides.
What does the reaction of an amine with a carboxylic acid form?
A carboxylic acid first adds to the DCC molecule to form a good leaving group, which can then be displaced by an amine during nucleophilic substitution to form the corresponding amide.
What is the reaction of amines with carboxylic acid?
The direct reaction of a carboxylic acid with an amine would be expected to be difficult because the basic amine would deprotonate the carboxylic acid to form a highly unreactive carboxylate.
However when the ammonium carboxylate salt is heated to a temperature above 100 oC water is driven off and an amide is formed.
