• W2048694792 abstract "Treatment of 1,8-bis(diphenylhydroxymethyl)naphthalene with a mixture of [HBF4]aq and (CF3CO)2O affords the corresponding dication, 1,8-bis(diphenylmethylium)naphthalenediyl (12+), which was isolated as the [BF4]- salt. This dication has been fully characterized, and its structure has been studied computationally. The 13C NMR resonance of the methylium centers appears at 207.7 ppm. As indicated by an X-ray single-crystal analysis, the vicinal methylium centers are separated by 3.112(4) Å. Dication (12+) reacts with fluoride to afford [1−F]+ which has been isolated as the [BF4]- salt. The fluorine atom of [1−F]+ is connected to one of the former methylium centers through a typical C−F bond of 1.424(2) Å and forms a long interaction of 2.444(2) Å with the other methylium center. While the structure of [1−F]+ can be largely accounted for by considering a simple methylium formulation, density functional calculations followed by an Atom In Molecules analysis as well as a calculation of the Boys localized orbitals indicate that the long C−F interaction of 2.444(2) Å corresponds to a dative bond. Hence, formulation of [1−F]+ as an unsymmetrical fluoronium must also be considered. As indicated by 1H NMR spectroscopy, the structure of this ion is fluxional; the fluorine atom oscillates between the former methylium centers with apparent activation parameters of ΔH⧧ = 52(±3) kJ mol-1 and ΔS⧧ = −18(±9) J K-1 mol-1 as derived from line shape analysis. This dynamic process, which has also been studied theoretically by B3LYP density functional theory and Møller−Plesset second-order perturbation theory methods, involves symmetrical fluoronium ions as low-energy transition states." @default.
