Heating the reaction mixture is sufficient to hydrolyze the amide back to the nitrated aniline. In the Wolfenstein-Boters reactionnitrating agents reacts with nitrating agents acid and mercury nitrate to give picric acid.

Ipso nitration[ edit ] With aryl chlorides, triflates and nonaflates ipso substitution can take place as well in so-called ipso nitration.

The ONOO- formation in vivo has significant implications in free radical biology. It exerts a nitrating agents role in large number of pathophysiological reactions and also acts as signaling molecule in activation of several protooncogenes.

Therefore, there is a great opportunity in the postgenomic period to understand the interplay of these molecular interactions with biological events such as apoptosis, gene regulation etc.

This review deals with biological significance of peroxynitrite, its precursors, reactions with large range of biomolecules, including aminoacids, proteins, lipids, nucleic acids, antioxidants as well nitrating agents cytotoxic aspects.

Nitration can be accelerated by activating groups such as aminohydroxy and methyl groups also amides and ethers resulting in para and ortho isomers.

According to another source [10] a more nitrating agents nitration of aniline starts with the formation of acetanilide by reaction with acetic anhydride followed by the actual nitration.

Because the amide is a regular activating group the products formed are the para and ortho isomers.
