Mechanistic Insights into the Interface??Directed Transformation of Thiols into Disulfides and Molecular Hydrogen by Visible??Light Irradiation of Quantum Dots
Abstract Quantum dots (QDs) offer new and versatile ways to harvest light energy. However, there are few examples involving the utilization of QDs in organic synthesis. Visible-light irradiation of CdSe QDs was found to result in virtually quantitative coupling of a variety of thiols to give disulfides and H 2 without the need for sacrificial reagents or external oxidants. The addition of small amounts of nickel (II) salts dramatically improved the efficiency and ...
