摘要

The oxidative polymerization of aryl sulfoxides provides a novel polysulfo-nium compound

poly(methylsulfonio-1

4-phenylenethio-1

4-phenylene cation) in quantita-tive yield. The polymerization proceeds efficiently in an acidic solution under atmosphericconditions. Oxygen

chemical and electrochemical oxidations are available. Vanadyl acety-lacetonate and cerium ammonium nitrate act as an effective catalyst for the oxygen ox-idative polymerization. The polymerization mechanism involves multielectron oxidation of the sulfides followed by successive electrophilic substitution.The resulting polyarylenesulfonium cations are useful as a soluble precursor for the synthesis of high molecular weight (Mw>105)poly(thio arylne)s.
