What are the reactions of amines?
- Some of the reactions of amines are described below: 1. Basic character of amines Amines, being basic in nature, react with acids to form salts. Amine salts on treatment with a base like NaOH, regenerate the parent amine. Amine salts are soluble in water but insoluble in organic solvents like ether.
What is the mechanism of amine deprotonation?
- • Mechanism: Required (addition-elimination-deprotonation) • Amine must have at least one hydrogen to begin. But 1º, 2º, or NH3all react well. • But 3º amines can’t work. • Some base is required for the deprotonation step and to absorb the HCl. For cheap amines, excess amine can simply be used.
What is the basic workup for amine and carbonyl reactions?
- (Basic workup) • The carbonyl reactant can be an aldehyde or a ketone • The amine reactant must have at least one hydrogen, as shown above; but R2 and/or R3can be either a carbon or a hydrogen. Thus: o NH3 ? 1º RNH2 o 1º RNH2 ? 2º R2NH o 2º R2NH ? 3º R3N
How do amines react with copper (II) ions?
- Just like ammonia, amines react with copper (II) ions in two separate stages. In the first step, we can go on using the Bronsted-Lowry theory (that a base is a hydrogen ion acceptor). The second stage of the reaction can only be explained in terms of the Lewis theory (that a base is an electron pair donor).
