In this manuscript, we report a radical type ring-opening of sulfonium salts with heteroarenes under visible light conditions. This developed method does not require noble metal photocatalysts, or stoichiometric amount of external oxidants, and has a application prospect in the synthesis of organosulfur compounds and bioactive molecules. This radical type ring-opening photocatalytic system could inspire further applications of sulfonium salts in C(sp³)−C(sp²) bond forming reactions.

铜光催化剂可见光诱导自由基型硫盐与杂芳烃开环

在这份手稿中，我们报道了在可见光条件下硫盐与杂芳烃的自由基型开环。该方法不需要贵金属光催化剂，也不需要化学计量的外部氧化剂，在有机硫化合物和生物活性分子的合成中具有应用前景。这种自由基型开环光催化体系可以激发硫盐在 C( sp ³ )−C( sp ² ) 键形成反应中的进一步应用。
