    Experimental evidences for unusual protonation of tetraethyl p-tert-butylcalix[4]arene tetraacetate and the most probable structure of the resulting complex

  • Original language description

    Using 1H and 13C NMR, FT IR spectroscopy and DFT calculations, it was shown that hydronium ion H3O+ forms an equimolecular complex with tetraethyl p-tert-butylcalix[4]arene tetraacetate in acetonitrile. In the complex, H3O+ is bound by three strong hydrogen bonds preferentially to the phenoxy oxygen atoms.

  • Czech description

    S použitím 1H a 13C NMR, FT IR spektroskopie a DFT výpočtů bylo ukázáno, že hydroniový iont H3O+ tvoří ekvimolekulární komplex s tetraethyl p-tert-butylkalix[4]aren-tetraacetátem v acetonitrilu. Iont H3O+ je v komplexu vázán třemi silnými vodíkovými vazbami, preferenčně ke kyslíkovým atomům fenoxy-skupin.
