Abstract
The coupling of 1-chloro-2,4-dinitrobenzene with 3,5-dichloroaniline gives 3,5-dichloro-2′,4′-dinitrodiphenylamine. The nitration of this formerly unknown compound with anhydrous nitric acid gives 3,5-dichloro-2,4-2′,4′-tetranitrodiphenylamine, in which the chlorine atoms are mobile and can be replaced by amino groups. The partial reduction of 2,4-dinitrodiphenylamine and its derivatives can be accomplished better with Na2S2 than with Na2S.
