Pyridylphosphonium salts, which are readily available and air thermally stable, have been used to effectively synthesize structurally diverse pyridines. Herein, we report the pnictogen bonding (PnB) enabled photoactivation of pyridylphosphonium salts with catalytic potassium carbonate generate pyridyl radical for pyridine synthesis. Remarkably, this light-driven transformation allowed chiral pool synthesis excellent chirality retention, giving a wide range selenium-containing On basis our combined computational experimental studies, propose that PnB between enables access photoactive charge transfer complex, is able undergo single electron its transformation.

We describe a simple and environment-friendly visible light-promoted protocol to access 2-aryl-(3-organoselanyl)thieno[2,3-b]pyridines, through the selenocyclization of 3-(arylethynyl)-2-(alkylthio)pyridines in presence diorganyl diselenides as selenium source. The Se-based reactive species were generated situ by homolytic Se-Se bond cleavage using blue LED an O2 atmosphere at room temperature. was suitable for wide range substrates bearing different substituents, allowing synthesis twenty-one thieno[2,3-b]pyridines good excellent yields (57–99%).
