Abstract
Endo-tetrahydrodicyclopentadiene is isomerized to its exo-isomer in the presence of aluminum trichloride at a temperature in the range between from about -.degree. C to about 90.degree. C. The mole ratio of AlCl.sub.3 to the tetrahydrodiene is in the range between from about 0.001 to about 0.75. An inert solvent may also be used. The very facile isomerization is essentially quantitative. The exoisomer has utility as a relatively high BTU/gallon, viscosity-lowering difluent for a missile fuel.
