New advances in N-oxidation of nitrogen-containing heterocyclic compounds

Heterocyclic N-oxides are important intermediates in organic synthesis and could be used as catalyst and explosive. New advances in N-oxidation nitrogen-containing heterocyclic compounds are reviewed. The reactions include N-oxide reaction of heterocyclic compound with one nitrogen, two nitrogen, or multi nitrogen and the reaction which can provide object product and N→O group at the same time. Especially, the N-oxide reaction of heterocyclic compounds with complicated structure is discussed.
