Abstract

In order to clarify the special properties of the aryl‐bound nitramino substituent NRNO~2~ (R = H, CH~3~), ^13^C and ^15^N NMR spectra of six nitraminobenzenes and nine nitraminopyridines were measured in DMSO‐d~6~ and their chemical shifts assigned. ^1^H NMR chemical shifts and spin‐spin coupling constants of all the compounds were also determined. In contrast to the behaviour of nitropyridines or ‐benzenes studied previously, most of the present compounds gave very broad ^17^O NMR lines even at elevated temperatures and their ^17^O NMR data were not useful for any reliable conclusions.
