Preceding papers on aromatic sulfurations have shown that a catalytic amount of iron powder promotes the reaction of aromatics with the compounds containing bivalent sulfur- chlorine bonds. The reactions with sulfur chlorides' and sulfenyl chlorides2 yield symmetric sulfides and asymmetric sulfides, respectively. On the other hand, benzenethiosulfenyl chlorides give disulfide or monosulfide depending on whether or not they have an ortho gr ...
