  1. Precursor of tetrafluoroborate salts of various stabilized cations. See, e.g.: Org. Synth. Coll., 5, 1135 (pyrylium), 1138 (tropylium); 6, 364 (sulfonium), 991 (cyclopropenium).
  2. Addition to aqueous solutions of aryldiazonium salts usually results in precipitation of the diazonium tetrafluoroborates, which are often stable enough to be isolated, and can undergo various reactions in non-aqueous solvents. For hydrodediazoniation in the presence of formamide, see: J. Chem. Soc., Perkin 1, 873 (1986). Probably their most important use is the Schiemann (or Balz-Schiemann) synthesis of aryl fluorides in which the tetrafluoroborate salt is heated neat or in an inert solvent. For examples, see: Org. Synth. Coll., 2, 188, 295, 299 (1943). Reviews: Org. React., 5, 193 (1949); Adv. Fluorine. Chem., 4, 1 (1965). See also Hexafluorophosphoric acid, L15728.
