Hindered aromatic nitroso-compounds, prepared by oxidation of the corresponding amines with m-chloroperoxybenzoic acid, were converted into N-arylhydroxamic acids which could be obtained only in poor yield or not at all by the conventional reduction of nitro-compounds.
Fluorenylhydroxamic acids isomeric with the carcinogens N-fluoren-2-ylacetohydroxamic acid. Part I. Synthesis of N-fluoren-1-yl-, N-fluoren-3-yl-, and N-fluoren-4-ylacetohydroxamic acid

Three new fluorenylhydroxamicacidsisomeric with the carcinogenN-fluoren-2-ylacetohydroxamicacid have been synthesized by partial catalytic reduction of the corresponding nitrofluorenes, prepared in turn by oxidation of the respective fluorenamines with peroxymaleic acid. A route to N([1-14C]fluoren-1-yl)acetamide and -acetohydroxamic acid by aromatization of the oxime of 3,4-dihydrofluoren-1 (2H)-one
