Copper, silver, gold, and rhodium compounds catalyze the rearrangement of diademane (1) to triquinacene (5) and snoutene (7), respectively.Known mechanism may be adopted to explain this behaviour.The catalytic hydrogenation of 1 leads to a mixture of 6 products, 9 - 14, the composition of which was independent of the extent of reaction.Adamantane, the thermodynamically most stable isomer of all conceivable "hexahydrodiademanes", was not detected.
Organic Peroxides, XIV. The Thermal Decomposition of Polycyclic tert-Butyl Bridgehead Peroxycarboxylates

Eleven bridgehead peresters (1, 2, 5 - 8, 10, 12, 14, 18, 21) have been prepared for the first time and the products and the kinetics of their thermal decomposition were investigated.The correlations of all known thermolysis constants of bridgehead peresters with the steric substituent constants φf, with the solvolysis constants of the corresponding bridgehead bromides, as well as with the change in strain enthalpy ΔHsp for hydride abstraction from the bridgehead, as calculated by the procedure of v.R.Schleyer, were analysed.The thermolysis constants of these peresters are mainly determined by the polar effect in the transition state of the perester fragmentation.
