摘要

在此，我们介绍了一种利用 Bi 量子点（QDs）作为催化剂，在温和条件下将硫醇光化学氧化偶联为二硫化物的高效合成方法。该方法催化剂载量低、反应设置简单、效率高。芳香族硫醇和脂肪族硫醇可以成功转化为二硫化物，而且产量很高，显示出对各种取代基和杂环的耐受性。此外，该方案还可扩展到不对称二硫化物的合成，并可进行克级规模的合成。

Photochemical oxidative coupling of thiols to disulfides using Bi quantum dots: Mild and efficient catalysis

Herein, we present an efficient synthesis method utilizing Bi quantum dots (QDs) as catalysts for the photochemical oxidative coupling of thiols to disulfides under mild conditions. The protocol offers low catalyst loading, simplicity in reaction setup as well as high efficiency. Aromatic thiols and aliphatic thiols are successfully transformed into disulfides with good to quantitative yields, demonstrating tolerance to various substituents and heterocycles. Additionally, the protocol extends to the synthesis of asymmetric disulfides and allows for gram-scale synthesis.
