Rearrangements of long-lived carbocations formed from endo-9-hydroxy-1,8,9,10,10,11,12-hepta-methyltricyclo[6.2.2.02,7]dodeca-2(7),3,5,11-tetraene in the system HSO3F-SO2ClF-CD2Cl2 at -95°C and having 6,7-benzobicyclo[3.2.1]octadiene and 5,6-benzotricyclo[3.2.1.02,7]octene structures were studied by 1H and 13C NMR spectroscopy. Degenerate rearrangements of similar cations derived under the same conditions from the 9-CD3-analog of the title compound were examined by the 2H NMR method. Raising the temperature results in formation of benzobicyclo[3.3.0]octadiene (benzopentalene) structures. The calculated (MINDO/3) heats of formation of isomeric carbocations are consistent with the experimental data. The mechanisms of the observed rearrangements are discussed.
