The Schiemann reaction (also called the Balz–Schiemann reaction) is a chemical reaction in which anilines (1) are transformed to aryl fluorides (3) via diazonium fluoroborates (2).[1][2] Named after the German chemists Günther Schiemann and Günther Balz, this reaction is the preferred route to fluorobenzene and some related derivatives,[3] including 4-fluorobenzoic acid.[4]

The Schiemann reaction

The reaction is similar to the Sandmeyer reaction, which converts diazonium salts to other aryl halides.[5]
