The initial rate of nitrobenzene hydrogenation catalyzed homogenously 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 systems, which does not catalyze hydrogenation of ortho-substituted nitrobenzenes.

A process for the preparation of α-methyl-carbazole-2-acetic acids, which comprises reacting an α-methyl-3-oxocyclohexane malonic acid di-lower alkyl ester with a substituted phenylhydrazine, and thereafter sequentially oxidizing and hydrolyzing the reaction product to obtain the desired acid, is described.
