The double bond in norbornene ring of TCPD was easily saturated at a low temperature, and an intermediate 12,13-dihydrotricyclopentadiene (12,13-DHTCPD) was formed. Higher temperature and hydrogen pressure were required for the saturation of remaining double bond in cyclopentene ring to generate a completely hydrogenated compound tetrahydrotricyclopentadiene.That is to say, the reaction occurred via the TCPD→12,13-DHTCPD→THTCPD route.
