Herein, we have developed naturally-occurring Emodin, which is commercially available at low-cost, as a novel organic photocatalyst for the first time. Emodin was successfully employed in the selective oxidation of sulfides promoted by visible-light, delivering valuable sulfoxides with high efficiency. Mechanistic investigations suggested both single-electron transfer (SET) and energy transfer (EnT) pathways might be involved in the oxidation reaction.
在此，我们首次开发了天然存在的大黄素（可低成本商业获取）作为一种新型有机光催化剂。大黄素成功用于可见光促进的硫化物选择性氧化反应，高效生成有价值的亚砜。机理研究表明，氧化反应可能涉及单电子转移（SET）和能量转移（EnT）途径。
