Description

General description

Tetrabutylammonium tetrafluoroborate is used as an electrolyte for the series of arylketone synthesis.

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.

Application

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).
