活性六元环- flp6与二氧化碳发生快速P/B加成反应。在高温下，得到的杂双环[2.2.2]辛烷衍生产物7开环并与环四聚体(7)4平衡。在大环结构中，4个单体六元环flp单元由4个co2分子连接形成超分子环体系。P/B环- flp6经历了多种附加环加成反应。
The active six-membered cyclo-FLP 6 undergoes a rapid P/B addition reaction to carbon dioxide. At elevated temperature, the resulting heterobicyclo[2.2.2]octane derived product 7 undergoes ring opening and equilibrates with the cyclotetramer ( 7 ) 4 . In the large macrocyclic structure, four monomeric six-membered cyclo-FLP units are connected by four CO 2 molecules to form the supramolecular ring system. The P/B cyclo-FLP 6 undergoes a variety of additional cycloaddition reactions.
