Abstract

The Balz-Schiemann reaction (first reported in 1927) [1] is a classical method for replacing the diazonium group (N 2 + ) by fluorine (fluorodediazoniation). The original procedure involved heating PhN 2 + BF 4 − without solvent. Despite the fact that this reaction has many drawbacks (see further), interest in the “Schiemann reaction” and its variants has not diminished over time because regiospecific fluorine introduction into aromatics, polyaromatics and ...
