Abstract

Tris(2,2′-bipyridine)ruthenium(II) chloride catalyzed the photo-oxidative polymerization of diaryl disulfides by O2, by which poly(thioarylene)s were efficiently produced. The polymerization proceeded through the electrophilic reaction of the sulfonium cation which was produced selectively by the photo-redox system.
