(Chemical Equation Presented) A series of N-substituted 2,4-dinitroimidazoles, 4,5-dinitroimidazoles, and 2-methyl-4,5-dinitroimidazoles have been selectively reduced to the corresponding aminonitroimidazole derivatives, using iron dust in glacial acetic acid at room temperature. 2,4-Dinitroimidazoles have been reduced to the 2-amino-4-nitro-derivatives only but 4,5-dinitroimidazoles have given 4-amino-5-nitro- or 5-amino-4- nitroderivatives depended on the structure of the N-substituent.

5(4)-Chloro-4(5)-nitroimidazole and 2-chloro-4(5)-nitroimidazole or their N-methyl derivatives have been synthesized in at least two independent routes.In contrast to some former reports it has been established that from 2,4(or 5)-dinitroimidazoles only 2-chloro-4(or 5)-nitroimidazoles are obtained.In 4,5-dinitroimidazoles only a nitro group in the 5-position is replaced by a chlorine atom.Structures of the obtained compounds have been confirmed by analyses of physico-chemical data.
