Sandmeyer Reaction

Sandmeyer Reaction

Named after:

Swiss chemist Traugott Sandmeyer in 1804, discovered the reaction and is hence named after him.

What is sandmeyer reaction

The Sandmeyer Reaction can be defined as a reaction in which we use aryl diazonium salts to obtain aryl halides. By implementing the sandmeyer reaction, one can implement transformations on benzene such as hydroxylation, trifluoromethylation, cyanation, and halogenation. The sandmeyer reaction can be stated as an example of a radical-nucleophilic aromatic substitution reaction.

Uses of Sandmeyer reaction

  • To convert aryl amines to phenols proceeding through the formation of an aryl diazonium salt.
  • To create aryl compounds functionalized by trifluoromethyl substituent groups
  • For the formation of benzonitriles.
  • To create aryl halides.
