Zinke nitration
From Wikipedia, the free encyclopedia
The Zinke nitration is an organic reaction in which a bromine substituent of a phenol or cresol is replaced by a nitro group by treatment with nitrous acid or sodium nitrite.[1] The reaction is a manifestation of nucleophilic aromatic substitution. The reaction is named after Theodor Zincke.
Two examples:[2]
and:[3]
The Zincke nitration should not be confused with the Zincke-Suhl reaction or the Zincke reaction.
