Answer:
Sandmeyer reaction →
It is used to synthesize aryl halides from aryl diazonium salts. It is an example of a radical-nucleophilic aromatic substitution.
When a primary aromatic amine, dissolved or suspended in cold aqueous mineral acid, is treated with sodium nitrite, a diazonium salt is formed. Mixing the solution of freshly prepared diazonium salt with cuprous chloride or cuprous bromide results in the replacement of the diazonium group by −Cl or −Br.
