Reações de 1,2-dicloro-4,5-dinitrobenzeno com aminas: monossubstituição de nitro e dissubstituição de cloro e nitro Reactions of 1,2-dichloro-4,5-dinitrobenzene with amines: monosubstitution of chlorine and disubstitution of chlorine and nitro
<abstract language="eng">1,2-dichloro-4,5-dinitrobenzene (DCDNB) reacts with primary and secondary amines, in acetonitrile, at room temperature, to give a monosubstituted nitro product with a yield of 85 to 95%. The chloro-nitro-disubstituted product is formed with excess amine under...
