Graphical Abstract
A zwitterionic construction has been synthesized that covalently links a trialkylsilylium cation and a weakly coordinating carborane anion in one neutral molecule (see X-ray structure; Si green, C gray, B orange, Cl red). The silylium character of this molecule is supported by DFT calculations (see LUMO), 29Si CP/MAS NMR spectroscopy, and reactivity.

- 29Warming up the SO2 solution of 3 to ambient temperature resulted in decomposition, although the diminished 1H NMR resonance of [(CH3)3C]+ could still be observed at 20 °C. Apparently, strong acid formation takes place, from the similarity of new downfield signals to the spectrum of F3CSO3H in liquid SO2. It is not clear whether degradation is owing to interaction with SO2, adventitious impurities, or the anion. Kato and Reed[27] also only observed [(CH3)3C][HCB11Me5Br6] in solution at −60 °C.
