Hexahydrogenated cyclooctatetraene dimer 1 (mp 41.5 °C) isomerized with Lewis acid catalyst to give two isomeric ethanodiam an tañes, 4 (Cd and 5 (Cs). Compound 4 is favored thermodynamically over 5 by a factor of 13 at 28 °C. The tetrahydrogenated cyclooctatetraene dimer 2 (mp 38.5 °C) likewise isomerized into two novel heptacyclohexadecanes, (C2)-bisethanobisnordiamantane ( 6) and a formal dimer of bicyclo[2.2.2]octadiene (7) with Did symmetry. Bromides from 6 and 7 were separated and their structures determined by X-ray analyses.
