Abstract:
Prolonged heating of benzene solution of hydroxamic acids (1:R=Bu , x=1-1), (1:R=But, X-P-MeO) & (1:R-But,, x=p-Noi.) causes these acids to rearrange to the corresponding O-benzoylhydroxamine. Reaction of an initially formed N-alkylhydroxylamine with 0,N-dibenzoyl-N-T-butylhydroxylamine to give both the hydroxamic acid and the O-acylhydroxylamine seems to represent the most satisfactory mechanistic interpretation of such rearrangements. The aditions of trifluoroacetic acid and pyridine to hydroxamic acids are also compared.
