Application

Sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate can act as a precursor to synthesize other tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (TFPB)-based reagents.[1][2][3][4]
The TFPB anion can be used to catalyze:
  • In-situ diazo-coupling and N- and C-nitrosations.[5]
  • Synthesis of oxirane from different carbonyl substrates and trimethylsulfonium chloride via phase-transfer catalysis.[6]
