Question

How will you prepare chlorobenzene from benzene diazonium chloride?

Answer 1

The Sandmeyer reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts. It is named after the Swiss chemist Traugott Sandmeyer. The reaction is a method for substitution of an aromatic amino group via preparation of its diazonium salt followed by its displacement with a nucleophile, often catalyzed by copper(I) salts. The nucleophile can include halide anions, cyanide, thiols, water, and others.

The substitution of an aromatic amino group is possible via preparation of its diazonium salt and subsequent displacement with a nucleophile.
