摘要

烷基和芳基硫化物可以在温和的无溶剂条件下氧化，选择性好。若氧化剂为溴酸钠与阳离子交换树脂的混合物，则产物为亚砜;如果是高锰酸盐和五水硫酸铜的混合物，则产物是砜。实验过程简单，所得产品接近定量产率，易于分离和纯化。

Selective oxidation of sulfides under solvent-free conditions

Alkyl and aryl sulfides can be oxidized under mild, solvent-free conditions with good selectivity. If the oxidant is a mixture of sodium bromate and cation exchange resin, the products are sulfoxides; if it is a mixture of permanganate and copper sulfate pentahydrate, the products are sulfones. The procedures are experimentally simple and the products, obtained in nearly quantitative yields, are easily separated and purified.
