Abstract

A new procedure was worked out for the isomerization of Binor S, the norbornadiene dimer (heptacyclo/8,4,0,0^2,12,0^3,8,0^4,6,0^5,9,0^11,13/tetradecane) with phosphorus pentoxide to obtain a mixture of hexacyclic olefins, viz. hexacyclo/8,4,0,0^2,7,0^3,14,0^4,8,0^9,13/tetradec-5-ene and hexacyclo/6,6,0,0^2,6,0^5,14,0^7,12,0^9,13/tetradec-3-ene, which serve as the starting material in the synthesis of triamantane.
