Cooperative Organosulfur/Photoredox Catalysis Enables Radical-Polar Crossover C(sp3)–N Coupling via Inner-Sphere Electron Shuttling Radical-polar crossover (RPC) is a valuable mechanistic tool for revitalizing traditional radical and polar chemistries by integrating them. However, transitioning from radical to polar pathways acros...

Profs. Hong and Lee at SNU unveil a cooperative catalytic system using organosulfur shuttling to enable inner-sphere C(sp³)–N coupling—bypassing redox limits for late-stage access to complex arylamines. doi.org/10.1021/jacs...

Counterintuitive Photochemistry of an Isolated Acridinyl Radical: ConPET via Preassembly Despite a Long-Lived Excited State Photoredox chemistry has seen a dramatic rise in popularity in recent years, but mechanistic understanding has persistently lagged behind reaction development itself. This is particularly true for the...
