Amination reactions are chemical processes where an amine group (-NH2) is introduced into a molecule. This transformation is significant in organic chemistry, as it helps create various compounds, including pharmaceuticals and agrochemicals. The reaction typically involves the substitution of a hydrogen atom in a substrate with an amine, leading to the formation of an amine product. These reactions can occur through different mechanisms, such as nucleophilic substitution or addition-elimination processes. Common reagents used in amination include ammonia (NH3) and primary or secondary amines. Understanding amination is crucial for synthesizing complex organic molecules and developing new materials.
