- 中文摘要: Endo-tetrahydrodicyclopentadiene (IV) is isomerized in the presence of trifluoromethanesulfonic acid (I) to give exo-tetrahydrodicyclopentadiene (V). At higher acid concentrations, the isomerization occurs instantaneously. The preferred molar ratio of I to IV is in the range 0.05 to 4.0 and the preferred temperature is in the range 20.degree.C to 100.degree.C. Under these conditions, virtually no admantane is formed and undesirable C/sub 10/H/sub 16/ isomers can be reduced to minimum. Besides the homogeneous system, the acid catalyst also works in a two-phase heterogeneous system. The spent acid in the heterogeneous system can be reused without losing catalytic effectiveness.
