What is the difference between a condensation reaction and an amidation?
A condensation reaction is a reaction in which two molecules combine to form a single molecule. An esterification is a condensation reaction in which an ester is formed from an alcohol and a carboxylic acid. An amidation is a condensation reaction in which an amid is formed from an amine and a carboxylic acid.
Which amine reacts with formaldehyde?
In the Mannich reaction, primary or secondary amines or ammonia react with formaldehyde to form a Schiff base. Tertiary amines lack an N–H proton and so do not react. The Schiff base can react with α-CH-acidic compounds ( nucleophiles) that include carbonyl compounds, nitriles, acetylenes, aliphatic nitro compounds, α-alkyl- pyridines or imines.
What happens when amine is primary?
When the amine is primary, its reaction takes a different course. We will look at an example where the R group is the phenyl group (a benzene ring), since that is the most important application of this reaction. The aromatic diazonium ions produced by this reaction are stable enough to persist in a cold acidic aqueous solution.
What is the difference between amine and alcohol?
Notice that a stronger base (amine) is used up and a weaker base (alcohol) is produced. Notice also that before the alcohol (leaving group) portion of the ester departs, it picks up an H + so that it can leave as the weak base alcohol (R'OH) rather than as the strong base alkoxide ion (R'O - ). Again, weaker bases make better leaving groups.
