DIAMINO-4-nitrobenzene

The condensation of 1,2-diamino-4-nitrobenzene with bornane-2,3-dione has been investigated.290 Catalytic hydrogenation of fenchone oxime (203 X = NOH) gives the imine (203 X = NH) exclusively, whereas camphor oxime gives only the exo-amine (204) reduction with di-isobutylaluminium hydride yields predominantly heterocyclic secondary amines thus (203 X = NOH) gives (205) as the major product together with (206) and (204) and its endo-isomer.291... 

Diamino-4-nitrobenzene can be prepared by the partial reduction of 2,4-dinitroaniline in alcohol solution using sodium hydrosulfide or ammonium sulfide. - The method described here is a modification of that given by Kehrmann. ... 

Paper chromatography of a-keto acids has also been achieved after conversion to other derivatives, especially nitroquinoxalinols through 1,2-diamino-4-nitrobenzene (H25, S27, T6).
