Photo‐oxidation of bis(3,5‐dimethylphenyl) disulfide proceeds in the presence of aromatic nitriles as sensitizers. Catalytic amounts of 9,10‐dicyanoanthracene act as an electron mediator of the transfer from the disulfide to oxygen in the presence of biphenyl as a co‐sensitizer. The photo‐redox system enabled an efficient formation of poly(thio‐2,6‐dimethyl‐1,4‐phenylene) through electrophilic reaction of the sulfonium cation produced in the photo‐oxidation.
