  • Electrochemical activation of organic disulfides for electrophilic substitution
    Patent number: 6432294
    Abstract: Electrochemical oxidation of organic disulfides is conducted in an electrolytic solution containing an arene (e.g., anthracene, acenaphthylene, phenanthrene), and depending on the arene used and/or the product desired, an organic base (e.g., pyridine) to effect the synthesis of organothiated products in good yields.
    Type: Grant
    Filed: December 14, 2000
    Date of Patent: August 13, 2002
    Assignee: The University of Arizona
    Inventors: Richard S. Glass, Viatcheslav V. Jouikov, Nina V. Bojkova
  • Electrochemically generated organothiating reagents and their use
    Patent number: 6207838
    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.
