Under acidic or basic conditions aqueous permanganate is a vigorous, nonselective reagent that may be used to oxidize a variety of organic functional groups (eg double and triple bonds, primary and secondary alcohols, sulfides, sulfoxides, and aldehydes). l The use of various nonaqueous solvents, in which permanganate may be dissolved with the aid of phase-transfer agents, modifies the reactivity and selectivity of permanganate to the extent ...
