  • Convenient mild fluorinating agent which can be handled in glass equipment (long-term storage in glass is not recommended):
  • Activated halides can be displaced to give the corresponding fluorides J. Fluorine Chem., 15, 423 (1980); 47, 467 (1990). Carbohydrate bromides or mesylates can be converted to fluorinated analogues with inversion of configuration: J. Fluorine Chem., 60, 49 (1993); Tetrahedron Lett., 31, 6527 (1990).
  • In the presence of NBS, alkenes undergo trans-fluorobromination in high yield: Synthesis, 562 (1987); Liebigs Ann. Chem., 849 (1995); Org. Synth., 76, 159 (1998). Vinyl oxiranes undergo ring opening to give fluorohydrins: J. Fluorine Chem., 70, 1 (1995); in the presence of NBS, fluorobromination of the double bond occurs instead: J. Org. Chem., 59, 5277 (1994).
  • A variety of compounds undergo electrochemical fluorination at activated positions. ɑ-Fluorinations of sulfides have been extensively studied by Fuchigami and others. The reaction usually requires the presence of an electron withdrawing group ɑ- to the sulfur atom, e.g. monofluorination of ethyl (phenylthio)acetate: J. Org. Chem., 56, 6731 (1991); 59, 5937 (1994); 60, 3459 (1995), and of phenylthio substituted nitrogen heterocycles including ?-lactams: Tetrahedron Lett., 33, 7017 (1992); J. Org. Chem., 57, 3755 (1992); 58, 4200 (1993).
  • For electrochemical fluorodeiodination of alkyl iodides, see: Synlett, 999 (2000). Fluorodesilylation in ?-lactams has also been reported: J. Chem. Soc., Perkin 1, 1327 (1995).
  • Excellent, selective reagent for cleavage of O-silyl groups in carbohydrates, nucleotides, cyanohydrins, etc.: Carbohydr. Res., 166, 309 (1987); J. Org. Chem., 52, 564 (1987); Bioorg. Chem. Med. Lett., 4, 1345 (1994); J. Am. Chem. Soc., 116, 4697 (1994). This has been exploited in a mild synthesis of substituted furans: Tetrahedron Lett., 37, 6065 (1996):
  • The Balz-Schiemann reaction of aryldiazonium fluoroborates with the reagent under ultrasound irradiation gives improved yields of aryl fluorides: Z. Chem., 26, 169 (1986).
  • For a review of the use of the reagent in synthesis, see: J. Prakt. Chem./ Chem. Ztg., 338, 99 (1996).
