stoichiometric amount of a strong oxidant and an expensive transition-metal catalyst. This work describes the first example of the electrochemical oxysulfuration reaction of olefins with thiols and nucleophilicoxygen sources. This electrochemical difunctionalization reaction is conducted under catalyst- and oxidant-free conditions, and shows good substrate generality, affording thio-substituted alcohols,
molecular-iodine-catalyzed radical reaction. This reaction involves hydroxysulfenylation of alkenes with disulfides in aqueous solution. Air is used as the oxidant without any additives. Control experiments indicated that the oxygen atom of products might come from O2. Both aryl alkenes and aliphatic alkenes were well tolerated in this transformation and afforded the corresponding products in moderate
