Trimethylsilyl- and dimethyl(1H,1H,2H,2H-perfluorooctyl)silyl substituents have been introduced in the para position of tetraphenylborate anions, resulting in enhanced solubility of their complexes n-Bu₄N[B(C₆H₄SiMe₂R-4)₄] (R = Me, CH₂CH₂C₆F₁₃) and [Rh(dppe)₂][B(C₆H₄SiMe₂R-4)₄] (dppe = 1,2-bis(diphenylphosphino)ethane, R = Me, CH₂CH₂C₆F₁₃) in apolar organic solvents.
