A NEW METHOD FOR DEOXYGENATION OF TERTIARY AMINE N-OXIDES WITH ACETIC FORMIC ANHYDRIDE

Article abstract of DOI:10.1246/cl.1985.1517

Trialkylamine N-oxides and N,N-dialkylarylamine N-oxides were readily deoxygenated with acetic formic anhydride in dichloromethane at room temperature to give the corresponding tertiary amines in high yields, while heteroaromatic N-oxide and sulfoxides were not affected.
