用PhIO/RuCl 2（PPh 3）3氧化硫化物产生砜。PhIO芳环上的吸电子取代基降低了体系的反应活性，提高了体系的选择性。因此，使用间碘酰苯甲酸，硫化物转化为亚砜。在相同的条件下，脂肪族伯醇与间碘酰苯甲酸转化为醛，而PhIO提供羧酸。
Oxidation of sulfides with PhIO/RuCl2 (PPh3)3 leads to sulfones. Electronwithdrawing substituents in the aromatic ring of PhIO reduce the reactivity and improves selectivity of the system. Thus, with m-iodosylbenzoic acid sulfides are converted to sulfoxide. Under the same conditions aliphatic primary alcohols are transformed to aldehydes with m-iodosylbenzoic acid, while PhIO affords carboxylic acids.
