O-Acylhydroxylamines. II. O-Mesitylene-sulfonyl-, O-P-Toluenesulfonyl-and O-Mesitoylhydroxylanine

摘要

O-Mesitylenesulfonyl and O-p-toluenesulfonylhydroxylamine have been prepared by the hydrofluoric acid and perchloric acid cleavages of the corres¬ponding t-butyl N-arenesulfonoxycarbamates. The structures of the O-arene-sulfonylhydroxylanines were established by (a) iodometric analysis, (b) reaction with acetone which gave the corresponding O-sulfonylacetoximes and (c) infrared examination. O-Mesitoylhydroxylamine was prepared similarly from t-butyl N-mesitoyloxycarbamiate. Reaction of O-mesitoylhydroxylamine with dibenzylamine gave l,l-dibenzylhydrazine.
