• Classical permanganate cleavage of olefins is difficult to control, and normally proceeds to the highest possible oxidation level. Adsorption of the reagent on moist alumina has been found to attenuate its activity and allow good yields of aldehydes to be obtained. This would appear to provide a possible alternative to ozonolysis for this conversion: J. Org. Chem., 58, 2918 (1993).
