Peroxytrifluoroacetic acid has been shown to be a useful reagent for the oxidation of aromatic amines to nitro compounds, olefins to epoxides, ketones to esters, 3 and N-nitroso compounds to N-nitro compounds. This reagent represents a distinct improvement over Car0 acid or peracetic acid for similar oxidations; for example, oxidation of aniline with Car0 acid is reported to give 1lyO of nitrobenzene in contrast to yields up to 89% realized by ...
