polysubstituted 2,6-cycloheptadien-1-ones gave bicyclo[3.2.0]hept-3-en-2-ones, lumiketone-like products, which subsequently photoisomerized to bicyclo[2.2.1]hept-2-en-7-ones. The reaction of cycloheptadienones to lumiketones was proven to proceed via a triplet excited state from both sensitization and quenching experiments.
与母体 2,6-cycloheptadien-1-one 不同,多取代的 2,6-cycloheptadien-1-ones 的紫外光照射产生双环 [3.2.0]hept-3-en-2-ones,lumiketone 样产物,随后光异构化为双环[2.2.1]hept-2-en-7-ones。环庚二烯酮与发光酮的反应被证明是通过敏化和淬灭实验的三重激发态进行的。
