Conformational changes in hydrazine and hydroxylamine derivatives studied by nuclear magnetic resonance spectroscopy
Abstract
The temperature dependence of the n.m.r. spectra of NN′-diaryl-NN′-dialkylhydrazines is consistent with a substantial barrier to rotation about the N–N bond, but similar temperature dependence of the n.m.r. spectra of NN-dialkylhydroxylamines may be associated with a high barrier to nitrogen inversion.
