A method for the electrochemical synthesis of sulfinic esters by aerobicoxidative coupling of thiophenols and alcohols has been developed. Using electrons as the redox reagent and O2 in air as the oxygen source, the reactions proceeded smoothly at room temperature, even for a gram-scale preparation. No use of catalyst, clean redox reagent, green and abundant oxygen source, and mild reaction conditions

A new protocol for SO bond formation was developed by electrochemical oxidative cross‐coupling between alcohols and thiophenols. With this strategy, a series of valuable sulfinicester derivatives were synthesized up to 96% yield from basic starting materials. A preliminary mechanistic investigation reveals that this reaction involves oxygen reduction reaction (ORR).
develop a simple and convenient method for the Ni/NHC-catalyzed cross-coupling of methyl sulfinates and amines without an acid/base to afford secondary or tertiary sulfinamides in moderate to good yields. The method can provide the desired products with broad substrate scope, good chemoselectivity and good functional group compatibility. The presented approach may enrich the Ni/NHC catalyst system and

cycloalkanes with alkylarylsulfinates has been performed. Using iodine as the catalyst, through C −H bond activation and sulfinates reduction, a wide range of thioethers were produced in moderate to high yields. Additionally, various thiocarboxylic esters can also be produced by simply performing the reaction under CO pressure. Notably, this is the first report in which alkylarylsulfinates were used as
