A catalytic amount of a sterically and electronically tuned diarylsulfonamide promoted allylic and benzylic C–H arylations in cooperation with a visible light photoredox catalyst. This is the first example of the catalytic use of a sulfonamidyl radical to promote the hydrogen atom transfer process.
催化量的空间和电子调谐的二芳基磺酰胺与可见光光氧化还原催化剂协同促进了烯丙基和苄基CH芳基化。这是催化使用磺酰胺基以促进氢原子转移过程的第一个例子。
