1-(N-Nitrosoalkylamino)benzimidazoles (7a-e) were prepared by nitrosation of the parent amines with nitrous acid. The NMR data revealed 7a- d in solutions as mixtures of E and Z-isomers due to hindered rotation around the N-NO bond. 1-(N-Nitrosoisopropylamino)benzimidazole (7e) existed in solutions as a sole Z-isomer. The rotation barrier around the N-NO bond was estimated for 7a by 1H NMR dynamic spectroscopy. The molecular structure of 1-(N-nitrosomethylamino)-2-methylbezimidazole (7d) was confirmed by X-ray structural data.
