Ammonium molybdate [Mo(VI)] is operationally simple, environmentally safe and inexpensive reagent. Regioselective nitration of anilides, non-activated and moderately activated aromatic compounds could be afforded by employing ammonium molybdate and nitric acid as mild and effective nitrating agent. This procedure works efficiently under reflux conditions to prepare mononitroderivatives of anilides, non-activated and moderately activated aromatic compounds in good to excellent yield with high regioselectivity.

The reactions of some ethyl N-arylcarbamates and of the corresponding acetanilides towards 1 equiv. of sodium nitrate in concentrated sulfuric acid at 0-5 deg have been compared with one another and have been found to exhibit significant differences.Except in the case of the unsubstituted analogues, nitration of the carbamates was found to occur significantly more quickly than that of the acetanilides as shown by (i) a representative competitive nitration, and (ii) the fact the carbamates containing a nitro group are nitrated smoothly whereas the corresponding nitroacetanilides are slow to react.On the basis of competitive reactions, it is suggested that this difference in reactivity is due to steric factors.

Peroxydisulfuric acid in sulfuric acid solution, prepared by reaction of hydrogen peroxide with excess oleum or 100percent H2SO4, oxidizes primary polynitroarylamines and their N-acetamido derivatives to polynitro aromatics in good to excellent yields.The new procedure is illustrated by the synthesis of several new polynitro compounds, not preparable by known synthetic methods.Peroxytrifluoromethanesulfonic acid is comparably efficient for such oxidations.The scope and limitations of the new reaction have been examined and compared to other methods of synthesis of polynitro compounds.
