Abstract

Functionally substituted N-nitrohydrazines were studied by heteronuclear NMR. It was shown that all the investigated products from nitration of the trimethylsilyl derivatives of functionally substituted hydrazines contain the N-NO2 fragment. The chemical shift of the nitrogen atoms of the hydrazine fragment in the15N NMR spectra and the\({}^1J_{15_N 15_N } \) spin-spin coupling constants were used as the main tests for structural identification. It was established that the number of recordable conformers decreases in the transition from the trimethylsilyl phenylhydrazine derivatives to the nitrohydrazines as a result of the conformational flexibility of the N(NO2)CO fragment.
