The isomerization of norbornadiene dimer, heptacyclo[8,4,0,02,12, 03,8,04,6,05,9,011,13]tetradecane (binor S), was studied in the presence of various catalysts. The isomerization resulted in a mixture of hexacyclic olefins (hexacyclo[8,4,0,02,7,03,14,04,8,09,13]tetradec-5-ene and hexacyclo[6,6,0,02,6,05,14,07,12,09,13]tetradec-3-ene), which is an important intermediate product in the five-stage synthesis of triamantane.
