NITROIMIDAZOLES. PART V. CHLORONITROIMIDAZOLES FROM DINITROIMIDAZOLES. A REINVESTIGATION

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.
