activation of thioethers to α-thio alkyl radicals and their addition to electron-deficient olefins to afford alkylated products through dual photoredox and weak Brønsted base catalysis. Mechanistic studies are consistent with a two-step activation mechanism, where oxidation of thioethers to their corresponding sulfide radical cations by an acridinium photoredox catalyst is followed with deprotonation by
