Editing Amine (section)

===Reductive routes===
Via the process of [[hydrogenation]], unsaturated N-containing functional groups are reduced to amines using hydrogen in the presence of a nickel catalyst. Suitable groups include [[nitrile]]s, [[organic azide|azide]]s, [[imine]]s including [[oxime]]s, amides, and [[Nitro compound|nitro]]. In the case of nitriles, reactions are sensitive to acidic or alkaline conditions, which can cause hydrolysis of the {{chem2|\sCN}} group. [[Lithium aluminium hydride|{{chem2|LiAlH4}}]] is more commonly employed for the reduction of these same groups on the laboratory scale.

Many amines are produced from aldehydes and ketones via [[reductive amination]], which can either proceed catalytically or stoichiometrically.

[[Aniline]] ({{chem2|C6H5NH2}}) and its derivatives are prepared by reduction of the nitroaromatics. In industry, hydrogen is the preferred reductant, whereas, in the laboratory, tin and iron are often employed.
