        • {ALF} Precursor of tetrafluoroborate salts of various stabilized cations. See, e.g.: Org. Synth. Coll., 5, 1135 (pyrylium), 1138 (tropylium); 6, 364 (sulfonium), 991 (cyclopropenium).
        • {ALF} 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.
