The method requires mild conditions, including visible light as a traceless green energy source, room temperature, eosin Y organic dye as a photoredox catalyst, ambient air as oxidant, and easily available starting materials to provide a green, efficient, metal- and strong-oxidant-free synthesis of 3-sulfenylindoles with broad substrate scope through vicinal thioamination of alkynes.1 aTambe, Shrikant, D.1 aRohokale, Rajendra, S.1 aKshirsagar, Umesh, A.  uhttps://library.ncl.res.in/content/visible-light-mediated-eosin-y-photoredox-catalyzed-vicinal-thioamination-alkynes-radical
