An efficient Fe(NO3)3·9H2O promoted ortho-nitration reaction of aniline derivatives has been developed. This reaction may go through a nitrogen dioxide radical (NO2) intermediate, which is generated by the thermal decomposition of iron(iii) nitrate. The practicality of the present method using nontoxic and inexpensive iron reagents has been shown by the broad substrate scope and applications.

A new and efficient Ag-catalyzed method for the nitration of anilides by using sodium nitrite as a cheap and available NO2 source has been developed. This C–H functionalization reaction is ortho-selective, achieves moderate to high yields and shows excellent functional group tolerance. Furthermore, it provides a novel approach to ortho-nitrated anilides, which are very tricky to access with traditional methods.
An aromatic iodination method, with iodic acid used as the only iodinating reagent

Benzene, halobenzenes, and a number of more or less deactivated arenes, including nitrobenzene, readily reacted in anhydrous HIO3/AcOH/ Ac2O/conc. H2SO4 mixtures to probably give ArIO2 intermediates or other hypervalent species (not isolated). The final reaction mixtures were poured into excess aq. Na2SO3 solution (a reductant) to give the purified iodinated products in 39-83% yields.
