Diethoxy disulfide (1) reacted with arylhydrazines to give arylbenzenes, diaryl sulfides, and aryl ethoxy tetrasulfides. The reaction of 1 with hydrazobenzenes gave azobenzenes in quantitative yields. The treatment of 1 with 1, 5-diphenylthiocarbonohydrazide or 1, 5- diarylthiocarbazones afforded 2, 3-diaryltetrazolium-5-thiolates.
