Abstract
The [(Me2CC5H4)2M]2+ and [(Me(H)CC5H4)2M]2+ dications (M=Ru, Os) were generated and their precursors, dicarbinols, were synthesized.1H NMR spectral analysis showed that the former dications have a dicarbocation structure. For the [(Me(H)CC5H4)2M]2+ dications, the energies of both the onium and dicarbocation structures are close, and compounds of both types can be simultaneously observed in solution.
