Electrophilic substitution in the benzene ring of indole

of nitration chemistry, as used in the manufacture of pharmaceutical intermediates; this is a broad area and so we can only skim the surface of this fascinating and diverse subject. Overview of nitration Nitration is simply defined as the introduction of the nitro functionality, -NO 2, into a molecule - most frequently by the electrophilic action of the nitronium ion (NO 2+). This type of

Nitration an overview ScienceDirect Topics

Benzene and benzene derivatives undergo electrophilic substitution rather than addition to maintain their aromaticity. In the nitration of benzene, anhydrous nitric acid reacts with sulphuric acid as a catalyst to form an electrophile which then attacks the benzene and attaches to it.

Nitration Methods and Mechanisms Request PDF

The mechanism for nitration of benzene: Step 1: Nitric acid accepts a proton from sulphuric acid and then dissociates to form nitronium ion. Step 2: The nitronium ion acts as an electrophile in the process which further reacts with benzene to form an arenium ion.
