In comparison to iodine(V) reagents such as 2-iodylbenzoic acid (‌75‌) and Dess–Martin per­iodinane (‌76‌) the reactivity of iodine(III) reagents toward alcohols is normally low and ­catalysts have to be employed in these reactions. Two reagents have proved appropriate for the oxidation of secondary alcohols: phenyliodine diacetate (‌81‌, R1 = H)[‌222‌,‌223‌] and iodosylbenzene (‌82‌; phenyliodane oxide),[‌224‌–‌226‌] which is readily prepared from the alkaline hydrolysis of phenyliodine diacetate (‌Scheme 54‌).
