Non-equivalence in NO-dialkyl-N-aralkylhydroxylamines: the N–O rotation versus N-inversion controversy
Abstract
Variable temperature 1H and 13C n.m.r. spectra of N-benzyl-NO-dimethyl- and NO-dimethyl-N-(1-arylethyl)hydroxylamines in deuteriotoluene are reported. The results are interpreted in terms of N-inversion rather than N–O rotation as the rate-limiting process governing the observation of non-equivalence.
