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
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
