In combination with phthalic anhydride is an effective mild and safe oxidant for N-heteroaromatic compounds and tertiary amines to N-oxides: Chem. Ber., 125, 1965 (1992) Can be used to generate the powerful oxidant peroxytrifluoroacetic acid from TFAA, avoiding the use of hazardous 90% H2O2: Tetrahedron Lett., 33, 4835 (1992). The same system has also been reported for oxidation of electron-deficient pyridines to the N-oxides: Tetrahedron Lett., 41, 2299 (2000). Similarly, performic acid can be generated in situ, providing a mild system for oxidation of aromatic aldehydes to benzoic acids: Synth. Commun., 31, 2195 (2001).
