research, the hexafluorocyclopentane-bridged bisbutatrienes were synthesized. They underwent various cyclizations to construct fulvene, pentalene, germacycle, benzocyclobutene, and cyclooctatetraene frameworks.
较长的累积烯在构建稠合 π 共轭体系中的合成应用引起了相当大的兴趣。最近,共轭双丁
三烯已被评估为较长累积烯的模拟物。在这项研究中,合成了六
氟环戊烷桥联的双丁
三烯。他们经历了各种环化来构建富烯、
戊烯、甲环、
苯并环丁烯和环辛四烯骨架。
