Polysulfide anions are endowed with unique redox properties, attracting considerable attentions for their applications in alkali metals-sulfur batteries. However, the employment of these anionic species in redox catalysis for small mol. synthesis remains underdeveloped due to their moderate-poor electrochem. potential in the ground state, whereas some of them are characterized by photoabsorptions in visible spectral regions. Herein, we disclose the use of polysulfide anions as visible light photoredox catalysts for aryl cross-coupling reactions. The reaction design enables single-electron reduction of aryl halides upon the photoexcitation of tetrasulfide dianions (S42-). The resulting aryl radicals are engaged in (hetero)biaryl cross-coupling, borylation, and hydrogenation in a redox catalytic regime involving S4• -/S42- and S3• -/S32- redox couples. In the experiment, the researchers used many compounds, for example, tert-Butyl 4-iodopiperidine-1-carboxylate(cas: 301673-14-3Electric Literature of C10H18INO2)
tert-Butyl 4-iodopiperidine-1-carboxylate(cas: 301673-14-3) is one of organic iodides. Organic iodides are used in veterinary products (Organic Iodide Powder) as a nutritional source of iodine. In the chemical industry, alkyl iodides serve as excellent alkylating agents and, specifically, methyl iodide is used as a methylating agent in the synthesis of various pharmaceutical drugs. Oceanic alkyl iodides are believed to be the principal source of atmospheric iodine.Electric Literature of C10H18INO2
