Russian Chemical Bulletin Aims and scope

Abstract

The NMR spectra (13C,15N, and14N) of N-nitropyrazoles containing nitro, methyl, and cyano groups in the pyrazole ring were investigated.13C NMR spectra were recorded under conditions of triple selective heteronuclear resonance13C-{1H,14N}. The effect of substituents in the pyrazole ring on the chemical shifts in the13C and15N NMR spectra is discussed. Coupling constants\(J_{13_C ,1_H } \) and\(J_{15_N ,1_H } \) obtained by the polarization transfer method [1H]→13C and [1H]→15N (INEPT, SPT) were measured and completely assigned.
