Abstract

Nitrogen inversion bat-piers in several acyclic dialkylhydroxylamines and their acetyl derivatives are determined by H-1 NMR band shape analysis. A barrier range of 50.0-57.7 kJ/mol is observed. The hydroxylamines with bulky substituents show a lower barrier. The smaller activation barrier for the acetyl derivatives reflects the dominance of pi-repulsive character of oxygen lone pairs in the transition state during nitrogen inversion.
