摘要：

Various ketones were smoothly converted into the corresponding alpha-tosyloxyketones with MCPBA and p-toluenesulfonic acid in the presence of a catalytic amount of ionic-liquid (IL)-supported PhI in room temperature ionic liquid, [emim]OTs. Moreover, the present ionic-liquid reaction media containing a catalytic amount of IL-supported PhI could be reused for the same alpha-tosyloxylation of ketones and thiazoles directly, keeping good yields.
