The Zincke nitration is a nitration reaction in which a bromine is replaced by a nitro group on an electron-rich aryl compound such as a phenol or cresol. Typical reagents are nitrous acid or sodium nitrite. The reaction is a manifestation of nucleophilic aromatic substitution and is named after Theodor Zincke, who first reported it in 1900.[1][2]
