a low potential for the synthesis of aryl sulfides from aryl thiols and electron-rich arenes has been developed. Cyclic voltammetry was carried out to investigate the electrocatalytic activity of KI for sulfenylation of 1,3,5-trimethoxybenzene. On the basis of in situ FTIR data, cyclic voltammetry and control experiments, the reaction mechanism involving redox chemistry of KI and generation of intermediate
