8-triene (7) in the vapour phase with UV light results in their isomerization to tetradecafluorotetracyclo[6,2,2,02,7,05,7]-dodeca-2,9-dienes (5 and 6) and dodecafluorotricyclo[5,2,2,02,6] -undeca-2,3,8-triene (8) respectively. The mechanisms of the isomerizations are discussed and it is concluded that 8 arises from 7 by way of a photochemical 1,5-sigmatropic migration of a fluorine atom. Vacuum pyrolysis
