The barriers to inversion in several acyclic di- and tri-substituted hydroxylamines are determined by 1H NMR band shape analysis.The barriers range from 49.1 to 66.8 kJ mol1- and are discussed in terms of a conformational process which involves nitrogen inversion and rotation around the N-O bond.The N-benzyl group with an ortho hydroxy substituent increases the nitrogen inversion barrier by 10 kJ mol-1, which indicates the requirement of breaking of the intramolecular hydrogen bond prior to inversion.
