Photolysis of bis(2,3-diphenylcycloprop-2-enyl)methane resulted in a novel intramolecular [2 + 2]-cycloaddition followed by a facile cycloreversion of the initially-produced quadricyclane to give tetraphenylbicyclo[2.2.1]heptadiene.
双(2,3-二苯基环丙-2-烯基)
甲烷的光解反应导致了新的分子内[2 + 2]-环加成反应,然后对最初生产的
四环烷进行了轻松的环还原,从而得到了四苯基双环[2.2.1]庚二烯。
