Synthesis of nitro compounds
Several primary aromatic amines were converted to their corresponding nitro compounds in good yields with sodium perborate tetrahydrate (SPB) in micellar media in the presence of a catalytic amount of tungstophosphoric acid (H3PW·nH2O).

The use of nonanebis(peroxoic acid) enables a regio- and chemoselective oxidation of aromatic amines hindered with an ortho substituent to the corresponding nitro compounds, except for anilines ortho-substituted with amino groups (NH2, NHR) or hydroxyl groups, where H-bonding between an hydrogen of the adjacent group and an oxygen atom from the diperoxy acid directs the oxidation.
