Webb23 apr. 2024 · Nitration of aromatic and heteroaromatic compounds has received a surging impact because nitroarenes are widely used as important intermediates and precursors during the synthesis of organic and organometallic compounds, pharmaceuticals, explosives, dyes, polymers, pesticides, plastics, drugs and medicines … WebbThis is an electrophilic aromatic substitution reaction involving the use of nitric acid and sulphuric acid. The nitric acid is protonated by the stronger sulphuric acid, forming an electrophilic nitronium ion and water. This nitronium ion then acts as the electrophile in the nitration, forming a bond with the π electrons of the aromatic ring.
