Studies in tertiary amine oxides. Part V—carbon-13 nuclear magnetic resonance spectra of someN-aryl tertiary amines, the correspondingN-oxides and the meisenheimer rearrangement products
摘要:
AbstractThe carbon‐13 NMR spectra of some N‐(2‐ or 4‐nitrophenyl) tertiary amines and their corresponding N‐oxides have been analysed. These N‐oxides undergo thermal rearrangement to O‐arylhydroxylamines, for which the 13C NMR spectral assignments were also carried out. The N‐oxidation effect on the aromatic and aliphatic fragments is calculated.
