摘要：

Polystyrene-supported pyrazolinium permanganate has been prepared and used as a new class of recyclable oxidizing reagent for alcohols. The reagent was found to be selective as it oxidized primary alcohols to aldehydes and secondary alcohols to ketones only. The effect of various reaction conditions such as the temperature, solvent, and molar concentration of the reagent was examined in order to find the optimum conditions. The spent pyrazolinium permanganate resin can be easily removed by filtration and can be recycled and reused.
