Oxidation of N-heterocycles by H2O2 catalyzed by a Mn-porphyrin: An easy access to N-oxides under mild conditions

Article abstract of DOI:10.1055/s-1997-1383

A variety of N-heteroaromatic compounds were converted into their corresponding N-oxides with good yields and with high chemoselectivity in tile presence of hydrogen peroxide as oxygen donor and a catalytic amount of Mn-porphyrin. The scope and limitation of this method are discussed.
