Herein, we report a mild metal-free visible-light-mediated allylation of thiols using an inexpensive photocatalyst (eosin Y). Photocatalytically generated sulfenyl radicals were coupled with allylic alcohols to obtain allylic sulfides in good to excellent yields. The reaction was found to be scalable and the products could be further functionalized. Furthermore, preliminary studies were carried out to gain insights into the reaction mechanism.

可见光介导的硫醇与烯丙醇的烯丙基化

在此，我们报告了一种温和的无金属可见光介导的硫醇烯丙基化反应，使用廉价的光催化剂（曙红 Y）。光催化产生的硫自由基与烯丙醇偶联，以良好到极好的收率获得烯丙基硫化物。发现该反应是可扩展的，并且产品可以进一步功能化。此外，还进行了初步研究以深入了解反应机理。
