Nitration of Toluene (Electrophilic Aromatic Substitution)
www.cerritos.eduElectrophilic aromatic substitution represents an important class of reactions in organic synthesis. In "aromatic nitration," aromatic organic compounds are nitrated via an electrophilic aromatic substitution mechanism involving the attack of the electron-rich benzene ring on the nitronium ion. The formation of a

The major products are those with substitution at the ortho and para positions. (This preference for o/p substitution makes the methyl group an ortho/para director).
