In this study, we present a novel photocatalytic-mediated approach for facilitating the [3 + 3] oxidative cycloaddition reaction of phenols and hydrazones. By utilizing visible light irradiation, this reaction is executed in an efficient, mild, and eco-friendly manner, without requiring any oxidants or additives. The versatility of this method is evidenced by the successful synthesis of 1,3,4-oxadiazine
在这项研究中,我们提出了一种新的光催化介导的方法,用于促进酚和腙的[3 + 3]氧化环加成反应。通过利用可见光照射,该反应以高效、温和且环保的方式进行,不需要任何氧化剂或添加剂。该方法的多功能性通过以令人满意的收率成功合成具有各种取代基的1,3,4-恶二嗪衍生物得到证明。此外,通过受控实验和密度泛函理论计算(DFT)阐明了反应的可能机制。
