Abstract
Diphenyl disulfides yield oligo(p-phenylene sulfides) by an anodic oxidation in CH 2 Cl 2 solution in the presence of protonic acids such as trifluoroacetic acid. The acid suppresses the nucleophilic reaction of the cationic active species and the electro-oligomerization of diphenyl disulfide proceeds through an electrophilic reaction of a cation formed anodic oxidation. The oxidation of diphenyl disulfide proceeds through a one-electron transfer and via phenylbis(phenylthio)sulfonium cation as an active species in this reaction. Upon adding benzoquinones and cerium acetylacetonate to the mixture, the oligomerization proceeds efficiently to give a high yield of the oligomer and can be carried out at a lower applied potential
