Borohydride exchange resin-copper sulfate in methanol readily deoxygenates quantitatively both tertiary amine N-oxides and heteroaromatic N-oxides at room temperature or under reflux. It tolerates many functional groups such as carbon-carbon double bond, chloride, epoxide, ester, amide, nitrile, sulfoxide, sulfone, and aliphatic disulfide moieties.
