Abstract
The reduction of sulfur-fluorine (S-F) bonds in pentafluorosulfanyl arenes, which is mediated by an electron donor-acceptor (EDA) complex, is described. Treatment of pentafluorosulfanyl arenes with allyltributylstannane and potassium iodide under photoirradiation conditions furnished allyl sulfides in up to 81% yield. The S-F bond reduction in pentafluorosulfanyl arenes was realized using only potassium iodide and visible light irradiation.
