Improved Electrochemistry in Low-Polarity Media Using Tetrakis(pentafluorophenyl)borate Salts as Supporting Electrolytes

Abstract

The noncoordinating anion [B(C(6)F(5))(4)](-) solubilizes cations and polycations, allowing the generation and study of such systems in low-dielectric media. Thus, when [NBu(4)][B(C(6)F(5))(4)] is used as a supporting electrolyte, cyclic voltammetry is possible in aliphatic ethers and other solvents of very low polarity.
