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
[reaction: see text] Heteroaromatic thioethers and aryl, heteroaryl, and alkenylstannanes participate in a palladium-catalyzed, copper(I)-mediated cross-couplingreaction at 50 degrees C in THF.
