Literature References

Thermal decomposition of diazonium hexafluorophosphates often gives better results in the synthesis of aryl fluorides than the classical Balz-Schiemann method via the tetrafluoroborates (see Tetrafluoroboric acid, L14037). For an example, see: Org. Synth. Coll., 5, 133 (1973).
