Process involves the continuous production of endo-endo stereoisomer of the hexacyclic dimer of norbornadiene using a three component catalystic system of diethylaluminum chloride, ferric acetylacetonate and triphenylphosphino. Temperature range of reaction is about 100 DEG -200 DEG F and residence time is about 1-10 hours. Process further involves taking a product stream, along with any catalyst and other materials, and treating it to deactivate the catalyst; then separating the desired endo-endo dimer by various means at a temperature below about 500 DEG F to avoid decomposition of iron salts. Unreacted norbornadiene is recycled.
