1,9-Bis(arylthio)dibenzothiophenes (1) and their minooxides (2) were prepared and the structures of the phenyl derivatives (1a) and (2a) were determined by X-ray crystallographic analysis.The dithia dications (3) were generated on dissolution of compounds (1) and (2) in concentrated sulfuric acid-d2 and their structures were characterized by 1H-nmr spectroscopy.
