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