Formation Mechanism of NF4+ Salts and Extraordinary Enhancement of the Oxidizing Power of Fluorine by Strong Lewis Acids

Formation Mechanism of NF4+ Salts and Extraordinary Enhancement of the Oxidizing Power of Fluorine by Strong Lewis Acids
Monica Vasiliu, David A. Dixon, Ralf Haiges, Karl O. Christe
The strongest known neutral one-electron oxidizers are reported by K. O. Christe and co-workers in their Communication (DOI: 10.1002/anie.201701784). The presence of strong Lewis acids enhances the oxidizing power of elemental fluorine by as much as 6.7 eV, and Sb2F11 has an electron affinity of 9.78 eV (PtF6: 7.09 eV). When combined with a typical lattice energy of about 6 eV for a solid product, these Lewis acid–fluorine adducts can “rob” an electron even from highly unreactive compounds and oxidize NF3 to NF3+, for example.
