The photolysis of substituted o-divinylbenzenes promotes a one-step and metal-free conversion to oxatricycles at room temperature. Irradiation o-divinylbenzenes results in an pericyclic reaction to form cyclic o-quinodiemthane intermediates, which subsequently undergo intramolecular oxa-[4+2] cycloaddition to form oxacyclic derivatives.
取代的邻二乙烯基苯的光解在室温下促进了一步且无金属的氧化三环转化。邻二乙烯基苯的辐照导致[4+2]环加成反应形成环状 o-醌二亚甲基中间体，随后这些中间体进行分子内氧化 [4+2]环加成反应，形成氧化环衍生物。
