text: Electrophilic amination reactions can be classified as either additions or substitutions. Although the resulting product is not always an amine, these reactions are unified by the formation of a carbon–nitrogen bond and the use of an electrophilic aminating agent. A wide variety of electrophiles have been used; for substitutions, these are most commonly amines substituted with electron-withdrawing groups: chloramines, hydroxylamines, hydrazines, and oxaziridines, for instance. Addition reactions have employed imines, oximes, azides, azo compounds, and others.
