Perfluorocyclopentadiene dimerises readily to perfluoro(tricyclo[5,2,1,02,6]deca-3,8-diene), the structure of which was proved by chemical methods and by infrared, nuclear magnetic resonance, and mass spectroscopy. Pyrolysis of the dimer effects its breakdown by a retro-Diels–Alder cleavage to perfluorocyclopentadiene, accompanied by elimination of difluorocarbene and formation of tetrafluoroethylene
全氟环戊二烯容易二聚为全氟(三环[5,2,1,0 2,6 ] deca-3,8-二烯),其结构已通过化学方法以及红外,核磁共振和质谱法证明。二聚体的热解通过逆Diels-Alder裂解为全氟环戊二烯而分解,同时消除二氟卡宾并形成四氟乙烯和全氟(bicyclo [4,3,0] nona-2,4,7-三烯)。最后的产品在低碳钢上的热解产生了全氟茚满和一种被认为是全氟茚满的化合物。
