Abstract

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 ...
