Abstract

The reaction of o-benzenedithiol with hexachlorobutadiene in the presence of triethylamine affords four products, in ratios dependent upon the experimental conditions employed. These products are assigned the structures of the tetrachloride 2, the isomeric dichlorides 4 and 5, and the fully substituted benzodithiine 3. Dichloride 4 is resistant to zinc reduction, whereas its isomer 5 is reduced by zinc to the corresponding dithiine derivative 7.
