A copper-catalyzed hydroxysulfenylation of α,β-unsaturated esters/amides is reported. The method presents a selective and efficient synthesis of β-hydroxysulfides bearing electron-withdrawing groups. The synthetic utility of this method is demonstrated by the concise synthesis of the anticancer drug bicalutamide.
phtocatalysts in organic synthesis due to their attractive properties in light absorption, photogenerated charge transportation, and utilization. We report herein the development of photoinduced selective oxysulfenylation of alkenes using CsPbBr nanocrystals that is visible light-responsive, easy-to-prepare, and cost-effective. Under blue light-emitting diode (LED), a series of alkene substrates are demonstrated

Controllingselectivity is of central importance to radical chemistry. However, the highly reactive and unstable radical intermediates make this task especially challenging. Herein, a strategy for taming radical redox reactions has been developed, in which solvent‐bonding can alter the reactivity of the generated radical intermediates and thereby drastically alter the reaction selectivity at room temperature
