A new method was developed for hydrogenation of unsaturated hexacyclic norbornadiene dimers, exo-exo-, exo-endo-, endo-exo-, and endo-endo- hexacyclo[,10.03,8.04,6.05,9]tetradec-12-enes, using sulfuric acid (98%), giving pentacyclo[,8.02,9.03,7]tetradecanes, which were subjected to skeletal rearrangement under the action of ionic liquids to form diamantane in up to 84% yield.

Keywords: diamantane; hexacyclic norbornadiene dimers, isomerization, ionic liquids, sulfuric acid
