Recently I am researching about TRISULFUR RADICAL-ANION; REDUCTION; SULFUR; TRANSITION; ACTIVATION; THIOLS; BOND; PHOTOCATALYSIS; SULFOXIDES; HALIDES, Saw an article supported by the Pharma Innovation Programme Singapore (A*STAR) [SERC A19B3a0014]. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Li, HY; Tang, XX; Pang, JH; Wu, XY; Yeow, EKL; Wu, J; Chiba, S. The CAS is 150-76-5. Through research, I have a further understanding and discovery of Mequinol. Category: indole-building-block
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 molecule synthesis remains underdeveloped due to their moderate-poor electrochemical 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 (S-4(2-)). The resulting aryl radicals are engaged in (hetero)-biaryl cross-coupling, borylation, and hydrogenation in a redox catalytic regime involving S-4(center dot-) and S-4(2-)/S-3(center dot-)/S-3(2-) redox couples.
