Final answer:
Amines can be produced through nucleophilic substitution reactions, where an alkyl halide reacts with ammonia or another amine, and through the reduction of nitriles by using hydrogen gas in the presence of a metal catalyst.
Step-by-step explanation:
Two reaction types that produce amines are nucleophilic substitution reactions and reduction of nitriles. In nucleophilic substitution reactions, amines are typically produced when an alkyl halide reacts with ammonia or another amine. For example, methyl bromide (CH3Br) reacting with ammonia (NH3) produces methylamine (CH3NH2) and hydrogen bromide (HBr). Another example is the reduction of nitriles. A nitrile, which is a compound containing the -C≡N functional group, can be converted into an amine through reduction. This is often done using hydrogen gas in the presence of a metal catalyst, like palladium on carbon (Pd/C). For example, benzonitrile (C6H5CN) can be reduced to benzylamine (C6H5CH2NH2) using this method.
