¹Н NMR SPECTRA OF SOME NITRO DERIVATIVES OF 2-ALKYLAMINO-, 2-РНЕNYLAМINO-, 2-РIРERIDYL-, 2-MORРНOLYL-, 2-(N-АLКYL-N-NIТRОSOАМINO)- AND 2-ALKYLNITRAMINO-4(ог 6)-МЕТНYLPYRIDINЕS

Abstract

¹H NMR spectra of some N-substituted 2-amino-3-nitro- and 2-amino-5-nitropyridines were measured and interpreted. Chemical shift assignments were based on existing chemical  shift rules for substituted pyridines and spectral comparison with compounds of similar structure. The splitting of the methyl group signal of the methylamino group into a doublet testifies that the investigated compounds exist in the amino form. Some ortho-amino- and ortho-alkylaminonitropicolines were found to give splitting of the amino signals due to intramolecular hydrogen bonding and steric hindrance.
