The oxidation of organo-sulfides to sulfones has been accomplished using an easily accessible bifunctional ionic liquid, [pmim]IO4 in the absence of any other oxidants, metal and organic solvent at ambient temperature. A variety of sulfides including dialkyl, aryl–alkyl, diaryl, and aryl–hetero aryl have been oxidized to the corresponding functionalized sulfones in high yields by this procedure.
在环境温度下,在不存在任何其他氧化剂,金属和有机溶剂的情况下,使用易于获得的双官能离子液体pmIO 4将有机硫化物氧化为砜。通过这种方法,包括二烷基,芳基-烷基,二芳基和芳基-杂芳基在内的各种硫化物已被高产率氧化为相应的官能化砜。
