Gomberg-Bachmann reaction



The Gomberg-Bachmann reaction, named for the Ukrainian-American chemist Moses Gomberg and the American chemist Werner Emmanuel Bachmann, is an aryl - aryl coupling reaction via a diazonium salt.[1][2][3]

The arene compound 1 (here benzene) is coupled with base with the diazonium salt 2 to the biaryl 3. Many aromats have been tested but yields are generally low (less than 40%) given the many side-reactions of diazonium salts. One intramolecular variation which gives better results is the Pschorr reaction.
