Question
Write a note on Sandmeyer's reaction.
Solution
Sandmeyer’s reaction:
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. This reaction is known as Sandmeyer’s reaction
