Abstract: The reaction of N, N-dimethylaniline (4) and aniline (5) with the Opivaloyl-N- arylhydroxylamines (la-f) in MeOH exhibits second-order kinetics and generates products of nucleophilic attack on the nitrogen of the hydroxylamine derivative. The characteristics of this reaction are not consistent with a nitrene or SET mechanism, an sN1 reaction with rate- limiting attack of the nucleophile, or nucleophile-assisted ionization. The only mechanism ...
