Paternò–Büchi reaction of aromatic double bonds with quinones under visible light irradiation. The reactions of aromatics with quinones exposed to blue LED irradiation yielded oxetanes at −78 °C, which was attributed to both the activation of double bonds in aromatics and the stabilization of oxetanes by thiadiazole, oxadiazole, or selenadiazole groups. The addition of Cu(OTf)2 to the reaction system at
本文报道了在可见光照射下芳香族双键与醌的 Paternò-Büchi 反应。芳香族化合物与醌在蓝光 LED 照射下发生反应,在 -78 °C 下生成氧杂环丁烷,这归因于芳香族化合物中双键的活化以及噻二唑、恶二唑或硒二唑基团对氧杂环丁烷的稳定作用。在室温下将 Cu(OTf)2 添加到反应体系中,通过铜催化氧杂环丁烷原位开环形成二芳基醚。值得注意的是,底物范围扩展到了一般芳烃。
