What is Kinetics and Mechanism of Hydrogenation of Nitrobenzene by [Diaquocobaloxime + Amine] System about?

The initial rate of nitrobenzene hydrogenation catalyzed homogeneously by cobaloximes is second order in cobalt and is inhibited by an excess of nitrobenzene. It also strongly depends upon cobaloxime : amino ratio. These observations were rationalized in terms of binuclear nitrobenzene-complexed intermediate as crucial in the catalytic cycle. This assumption was further supported by the unusual selectivity of cobaloxime system, which does not catalyze hydrogenation of ortho-substituted nitrobenzenes.
