The rctt isomer of tetrapyridylcyclobutane prepared from the solid-state [2 + 2] cycloaddition reaction of [bpeH(2)] x 2 CF(3)CO(2) [bpe = 1,2-bis(4-pyridyl)ethene] undergoes isomerization reaction to the rtct isomer in 100% yield, and this tetrahedral tetrapyridyl ligand forms two metal-organic frameworks having ptt and pts topology.
由[BPEH(2)] x 2 CF(3)CO(2)（BPE=1,2-双(4-吡啶基)乙烯）的固态[2+2]环加成反应制备的四吡咯环丁烷 rctt 异构体以 100%的产率进行异构化为 rtct 异构体，这种四面体型四吡咯配体形成了具有 ptt 和 pts 拓扑结构的两个金属有机骨架。
