Presented is a light-promoted C–C bond forming reaction yielding sulfone and phosphate derivatives at room temperature in the absence of metals or photoredox catalyst. This transformation proceeds in neat conditions through an auto-oxidation mechanism which is maintained through the leaching of trace amounts of O2 as sole green oxidant.
提出了一种光促进的 C-C 键形成反应,在室温下、在没有金属或光氧化还原催化剂的情况下产生砜和磷酸盐衍生物。这种转化通过自动氧化机制在纯净的条件下进行,该机制通过浸出痕量的O 2作为唯一的绿色氧化剂来维持。
