Abstract
Electrolysis of organic disulfides in liquid sulfur dioxide is used to obtain organothiating agents, which can then be reacted with appropriate substrates to effect the synthesis of organothioaromatic compounds efficiently and in high yields. With appropriate phenolic compounds, regioselective substitution occurs in which para substitution greatly exceeds ortho substitution.
