cercosporin at aspects of photophysics and photobiology, its application in photocatalysis has been rarely reported. Herein we report cercosporin‐photocatalyzed selective synthesis of aryl sulfides undermild and green conditions. The gram‐scale reaction can proceed using cercosporin‐containing fermentation supernatant without purification.
The C–S bond formation from arylhalides and thiols has been well established under various catalytic systems. In this work, user-friendly sulfinates have been exploited as an efficient sulfenylating reagent in the C–Scouplings through visible-light-induced photo/nickel dual catalysis under base- and external reductant-free conditions. A large number of aryl sulfide products were accessed with high
