General description

Tetrabutylammonium tetrafluoroborate (TBATFB) is a phase transfer catalyst. It can be synthesized by the reaction between 30% aqueous solution of tetrafluoroboric acid and 40% aqueous solution of tetrabutylamonium hydroxide. Tetrabutylammonium tetrafluoroborate acts as an electrolyte and inhibits the self-assembly of alkylthiosulfate on gold.


Tetrabutylammonium tetrafluoroborate may be used in the following studies:
  • As supporting electrolyte in the voltammetric determination of Δ(9)-tetrahydrocannabinol (Δ(9)-THC).
  • Synthesis of biologically relevant macrolactones, Sansalvamide A.
  • As supporting electrolyte in the determination of the oxidation and reduction potentials of 5,10,15,20-tetra[3-(3-trifluoromethyl)phenoxy]porphyrin by cyclic voltammetry.
  • Preparation of 1:1 adduct with 1,10-phenanthroline.
  • Used to prepare other tetrabutylammonium salts in aqueous solutions.
  • As electrolyte additive in the synthesis of conducting poly(thiophenes).

Spontaneous self-assembly of alkylthiosulfates on gold produce monolayers similar to the corresponding alkanethiols. Alkylthiosulfate self-assembly from THF solutions is inhibited in the presence of tetrabutylammonium tetrafluoroborate electrolyte. The mechanism of alkylthiosulfate self-assembly and the role of electrolyte and trace water...
