General description

1,2-Dinitrobenzene (o-Dinitrobenzene) is one of the nitroaromatic compounds present in urine which has been studied using gas chromatography-mass spectrometry-selected ion monitoring methods†. The electrochemistry of 1,2-dinitrobenzene (o-Dinitrobenzene) is strongly affected by 1,3-diphenylurea.

Application

  • A highly divergent Pictet-Spengler approach for pyrrolo quinoxalines from aryl amine using 1,2-dinitrobenzene as an oxidant: Discusses the utility of 1,2-dinitrobenzene as an oxidant in organic synthesis, relevant for developing novel pharmaceuticals (Pardeshi et al., 2019).

[reaction: see text] The electrochemistry of 1,2-dinitrobenzene (1,2-DNB), 1,3-dinitrobenzene (1,3-DNB), and 1,4-dinitrobenzene (1,4-DNB) is strongly affected by the presence of 1,3-diphenylurea. In DMF, the second reduction potential of all three DNBs shifts substantially positive in the presence of the urea
