General description

1,3-Dinitrobenzene can undergo reductive degradation by alkaline ascorbic acid to produce 1,3-phenylenediamine.[1]

Application

1,3-Dinitrobenzene can be used as a reactant to synthesize:      
  • 2′,6′- dinitrobiphenyl-4-ol and 1-nitrodibenzofuran via copper-catalyzed regioselective cross-coupling reaction with 4-iodophenol and 2-iodophenol respectively.[2]      
  • 1H-indazole derivatives by reacting with various N-tosylhydrazones in the presence of a base catalyst.[3]      
  • 3-(1H-Tetrazol-1-yl)benzenamine by reacting with triethyl orthoformate and NaN3 in the presence of a three-functional redox catalytic system.[4]
