BALZ-SCHIEMAN REACTION

Balz-Schiemann Reaction





The conversion of aryl amines to aryl fluorides via diazotisation and subsequent thermal decomposition of the derived tetrafluoroborates or hexafluorophosphates. The decomposition may also be induced photochemically.



Mechanism of the Balz-Schiemann Reaction



The mechanism of the Balz-Schiemann reaction remains obscure. A possible pathway is shown below:
