In Conjunction with an attempt to prepare hydrazobenzene by alkaline sulfide reduction of nitrobenzene, the reduction of azoxybenzene, a reduction intermediate, has been studied kinetically under the synthetic conditions. The rates of reduction are markedly affected by the solubility or the dispersibility of azoxybenzene in the solution of reducing agent. During the course of reaction, the product hydra-zobenzene is again oxidized to azobenzene by the disulfide formed through autoxidation of hydrosulfide.
