3/?s=1" target="_blank">1,3-Dinitrobenzene is one of three isomers of dinitrobenzene, with the formula C6H4(NO2)2. It is one of three isomers of dinitrobenzene. The compound is a yellow solid that is soluble in organic solvents.
Preparation
3/?s=1" target="_blank">1,3-Dinitrobenzene is accessible by nitration of nitrobenzene. The reaction proceeds under acid catalysis using sulfuric acid. The directing effect of the nitro group of nitrobenzene leads to 93% of the product resulting from nitration at the meta-position. The ortho- and para-products occur in only 6% and 3/?s=1" target="_blank">1%, respectively.
Reactions
Reduction of 3/?s=1" target="_blank">1,3-dinitrobenzene with sodium sulfide in aqueous solution leads to 3-nitroaniline. Further reduction with iron and hydrochloric acid (HCl) gives m-phenylenediamine.
