Alfonzo, Edwin published the artcileα-Heteroarylation of Thioethers via Photoredox and Weak Bronsted Base Catalysis, HPLC of Formula: 220655-09-4, the main research area is Heteroarylation thioether photoredox weak Bronsted base catalysis; Classical Minisci Reaction with Thioethers.
We report the C-H activation of thioethers to α-thio alkyl radicals and their addition to N-methoxyheteroarenium salts for the redox-neutral synthesis of α-heteroaromatic thioethers. Studies are consistent with a two-step activation mechanism, where oxidation of thioethers to sulfide radical cations by a photoredox catalyst is followed by α-C-H deprotonation by a weak Bronsted base catalyst to afford α-thio alkyl radicals. Further, N-methoxyheteroarenium salts play addnl. roles as a source of methoxyl radical that contributes to α-thio alkyl radical generation and a sacrificial oxidant that regenerates the photoredox catalytic cycle.
