Application

Reactant for:
  • Halide-induced ring opening of 2-substituted aziridinium salts
  • Synthesis of fluoro aromatics via fluorodenitration reactions
  • Synthesis of sevoflurane in ionic liquids by halogen-exchange fluorination
  • Synthesis of fluorinated Poly(oxomolybdates)
Tetramethylammonium fluoride may be used in combination with sulfuryl fluoride for the conversion of aryl phenols to aryl fluorides. It can react with aminosilanes to generate onium amide bases in situ, which can deprotonate heteroarenes.
Useful for halogen exchange.
