Regioselective arylthiolations of aromatic amines, arenols and ketones via C–H bond functionalization have been achieved with I2 and PPh3 in an aqueous system, whereby arylsulfenyl radicals are in situ generated from odorless sodium arylsulfinates. The arylsulfenyl radicals can react with free anilines containing electron‐withdrawing groups and complex substrates (estrone and progesterone). Further
We report the first example of highly enantioselective synthesis of structurally diverse chiral dithioketalsviaasymmetric sulfenylation of various types of S-based nucleophiles, catalyzed by a cheap cinchona alkaloid derivative, dihydroquinine.
