Reaction of Nitrobenzene with Polyamine Cobalt (II) Complexes

Abstract

The reaction of nitrobenzene with polyamine cobalt (II) complexes in aqueous solution under nitrogen atmosphere was investigated. Polyamine in the complexes was ethylenediamine, di ethylenetriamine, triethylenetetramine or tetraethylenepentamine. Azoxybenzene was produced selectively. The products were in better yield when the molar of pplyamine to cobalt was 3: 1. Mechanisms for these reactions were proposed and discussed.
