Electron donor–acceptor (EDA) complex mediated visible-light driven sulfur–fluorine bond reduction of pentafluorosulfanyl arenes using potassium iodide

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.
