Selective, heterogeneous oxidation of alcohols and diols with potassium permanganate
Abstract
Primary alcohols can be conveniently oxidized to carboxylic acids using solid KMnO4/CuSO4·5H2O/KOH in an organic solvent; 1,4- and 1,5-diols can be selectively oxidized to the corresponding lactones using appropriate mixtures of KMnO4/CuSO4·5H2O without added base.
