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
用PhIO / RuCl 2(PPh 3)3氧化硫化物可生成砜。PhIO的芳环中的吸电子取代基降低了反应活性并提高了系统的选择性。因此,与米-iodosylbenzoic酸硫化物转化为亚砜。在相同条件下的脂族伯醇转化到与醛米-iodosylbenzoic酸,而得到PhIO羧酸。
