Question

explain the term sandmeyer's reaction

Answer 1

The substitution of an aromatic amino group is possible via preparation of its diazonium salt and subsequent displacement with a nucleophile (Cl-, I-, CN-, RS-, HO-). Many Sandmeyer Reactions proceed under copper(I) catalysis, while the Sandmeyer-type reactions with thiols, water and potassium iodide don't require catalysis.the Sandmeyer Reaction is a very important transformation in aromatic chemistry, because it can result in some substitution patterns that are not achievable by direct substitution

Answer 2

The Sandmeyer reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts. It is an example of a radical-nucleophilic aromatic substitution.
