Electrochemical Activation of Sulfur-Synthesis of Organic Mono and Trisulfides with a Sacrificial Carbon-Sulfur Anode

Abstract

The electrooxidation of sulfur in organic solvents leads to the formation of the cationic species S²⁺ Macroscale electrolyses are carried out with a sacrificial carbon-sulfur anode. S²⁺ can react either with aromatics to give monosulfides by electrophilic substitution, or with nucleophiles, thiols for example, to give trisulfides.
