employing a simple strategy of reacting SO<sub>2</sub> gas with
easily attainable hydride donors such as 2-substituted-1,3-dimethyl-2,3-dihydro-1<i>H</i>-benzo[<i>d</i>]imidazole, benzimidazoline and
SO<sub>2</sub> were converted into benzimidazolium bisulfate at room
temperature and atmospheric pressure. Bisulfate originated from SO<sub>2</sub> and hydride from benzimidazoline and aerial oxygen. Metastable
dimers of bisulfate anions were observed in the solid state and in
solution where the anions are not stabilized by encapsulation in cages
but through hydrogen bonding from benzimidazolium cations. All three
benzimidazolines and resulted benzimidazolium bisulfates have been
characterized using <sup>1</sup>H and <sup>13</sup>C NMR spectroscopy,
high-resolution electrospray ionization mass spectrometry, and single
crystal X-ray diffraction techniques.
