✦ Synopsis

Swmnary: Potassium permanganate adsorbed on solid supports can be used to oxidize unsaturated secondary alcohols to the corresponding ketones without degradation of the carbon-carbon double bonds. The adsorption of reagents onto solid supports is known to induce changes in the reactivity and selectivity of a number of important reactions including substitutions, eliminations, additions, reductions and oxidations'. Although in the majority of these reactions organic polymers are used for solid supports it has been observed that inorganic solids are preferable for use with permanganate2. Because this reagent is a strong oxidant it rapidly degrades most organic polymers3. Previous reports have described the use of hydrated molecular sieves, alumina and copper sulfate as solid supports for the oxidation of secondary alcohols to ketones2. Primary alcohols (other than benzyl alcohol) were observed to give very low yields.
