What cannot be accomplished in solution is readily achieved in the gas phase by “charge-stripping” mass spectrometry: generation of dications from radical cations of acyclic thioethers (e.g., 1 2). Ionization energies for the oxidation are in good agreement with the predictions of qualitative MO treatments of the bonding in three-electron two-center radical cations.
