摘要

在这项工作中，我们描述了一种温和的、负担得起的、可见光介导的硫醇与相应的二硫化物的氧化偶联，利用一种市售的、无金属的光催化剂。在这里，我们展示了荧光素作为可见光驱动硫醇氧化偶联的光氧化还原催化剂的使用。硫氰酸铵作为氧化剂，反应条件温和，底物范围广，表明该技术是可行的二硫化物合成。

Visible-light induced oxidation of thiols to disulfides using fluorescein as a metal free catalyst

In this work, we describe a mild, affordable, and visible-light-mediated oxidative coupling of thiols to the corresponding disulfides utilizing a commercially available, metal-free photocatalyst. Herein, we demonstrate the use of fluorescein as a photoredox catalyst for visible-light-driven oxidative coupling of thiols to disulfides. The use of ammonium thiocyanate as an oxidant, mild reaction conditions, and a wide range of substrates suggest that this technology is feasible for disulfide synthesis.
