Odorless, Regioselective Synthesis of Diaryl Sulfides and α-Thioaryl Carbonyls from Sodium Arylsulfinates via a Metal- Free Radical Strategy in Water

Regioselective arylthiolations of aromatic amines, arenols and ketones via C–H bond functionalization have been achieved with I2and PPh3in 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 experiments and quantum chemical calculations were also performed to deduce a mechanism for the formation of arylsulfenyl radicals. (Figure presented.).

Polymer-supported Periodate and Iodate as Oxidizing Agents

The periodate forms of some commercial macroporous anion-exchange resins can be used in either protic or aprotic solvents to oxidize various quinols, catechols, and glycols and also triphenylphosphine, hydrazobenzene, and benzohydroxamic acid.The reagents in methanol oxidize thioethers.Polymer-supported iodate also oxidizes quinols and catechols.
