Versuchsvorschrift

1.2 g of sodium hydroxide and 0.25 g of Raney nickel are added to a suspension of 53.4 g of 3,3'-dichloroazoxybenzene in 60 ml of methanol and 15 ml of water and the hydrogenation reaction is carried out under a hydrogen pressure of 10 bars. After 90 minutes the mixture is cooled to 10° C. and the product is isolated by filtration. 3,3'-Dichlorohydrazobenzene is obtained in a yield of 89% of theory.
