Heteroaromatic sulfoxides are a frequent structural motif in natural products, drugs, catalysts, and materials. We report a metal‐free visible‐light‐accelerated synthesis of heteroaromatic sulfoxides from sulfinamides and peroxodisulfate. The reaction proceeds at room temperature with blue‐light irradiation and allows the C−H sulfinylation of electron‐rich heteroarenes, such as pyrroles and indoles
杂芳族亚砜是天然产物,药物,催化剂和材料中的常见结构基序。我们报道了由次亚酰胺和过二硫酸盐的无金属可见光加速杂芳族亚砜的合成。该反应在室温下用蓝光照射进行,并允许富电子杂芳烃(例如吡咯和吲哚)的C H亚磺酰化。基于底物范围,取代选择性和与不同亲核试剂的竞争实验,提出了亲电芳香取代机理。
