It was found that uncharged bisphenyliodonium derivative [1,10-(IPh)₂B₁₀H₈]⁰ undergoes a nucleophilic substitution with the [K(18-crown-6)]⁺F⁻ complex to form monofluoro derivative [1-IPh, 10-FB₁₀H₈]⁻, whereas the anionic Bu₄N[1-B₁₀H₉Ph] does not react with the complex. This charge-dependent reactivity, as well as solvent effects, was explained using DFT and QTAIM calculations, revealing the crucial role of iodine sigma-hole availability and competitive solvation. The structures of the key products were confirmed by multinuclear NMR spectroscopy and single-crystal X-ray diffraction.en1099-06822026241341013427American Chemical Society (ACS)DerivativesFluorine compoundsHalogenationNegative ionsSingle crystalsX ray diffractionNatural Sciences and Mathematics::540: ChemistryJournal Article10.1021/acs.inorgchem.6c01289
