A visible-light-induced desulfonylative Giese-type reaction has been developed. Essential to the success is the employment of Hantzsch ester to activate benzothiazole sulfones without any heavy-metal additives. Not only benzylic benzothiazole sulfones but also alkyl ones were viable substrates and reacted with electron-deficient alkenes and a propiol amide.
可见光诱导的去磺酰基 Giese 型反应已经被开发出来。成功的关键是使用 Hantzsch 酯激活苯并噻唑砜，而无需任何重金属添加剂。不仅苄基苯并噻唑砜，而且烷基苯并噻唑砜也是可行的底物，与缺电子的烯烃和丙炔酰胺反应。
