Nitric Acid (HNO3)
Nitric acid reacts violently with many organic substances. Acid concentration and temperature are important parameters allowing the control of the oxidation reactions.

A chemoselective and efficient procedure allows the conversion of benzylic
and allylic alcohols into the corresponding carbonyl compounds with sodium
nitrate as oxidant in the presence of 3-methylimidazolinium hydrogensulfate.

A mixture of nitrate salt and chlorotrimethylsilane is a mild and efficient
reagent for the direct oxidative chlorination of thiols and disulfides to the
corresponding sulfonyl chlorides in excellent yields. Sulfides and sulfoxides
were also found to undergo oxidation to sulfones. In most cases these reactions
are highly selective, simple, and clean, affording products in high yield and
purity.
