Alumina-assisted oxidation and reduction reactions can be performed with the addition of other reagents. Oxidation of sulfides 5 to sulfoxides 6 with alumina and sodium periodate in ethanol has been reported (Scheme 2).[‌22‌] The reaction can be performed at room temperature and there is no need to measure the amount of sodium periodate accurately. It has been shown that the sulfone does not form.
