ABSTRACT:
The reduction of azoxybenzene, azobenzenes and mixtures of azoxybenzenes and azobenzene to the hydrazobenzenes is possible under mild conditions, with high yields and without any great excess of reducing agents in the presence of raney-nickel and compounds which have an alkaline action with hydrogen or hydrazine hydrate.
