Aryldiazonium Salt Reactions in Aromatic Substitution

Aryldiazonium salts are useful starting materials in aromatic substitution reactions. They form when arylamines are treated with nitrous acid. In these salts, the diazonio group can be replaced by other nucleophiles to make many substituted benzenes.

A key reason this reaction works is that the l...

Aryldiazonium salts—prepared from an arylamine and nitrous acid—can undergo substitution reactions involving the displacement of the diazonio group with a nucleophile.

The easy elimination of the nitrogen molecule drives the substitution reaction.

Aryldiazonium salts are versatile intermediates as the diazonio group can be replaced...
