Abstract

It is shown that 4(5)-(4-alkoxyphenyl)-5(4)-nitroimidazoles are obtained when 4(5)-(4-alkoxyphenyl)imidazoles are refluxed with 3–4 N nitric acid. The use of concentrated nitric acid (d 4 20 1.42, 1.46) leads to di- and trinitro-substituted phenylimidazoles. The mass spectra of the nitro derivatives were studied, and the principles of the fragmentation were ascertained.
