摘要

Potassium peroxymonosulfate or oxone®, which is commercially available in the form of a triple salt 2KHSO 5 ·KHSO 4 ·K 2 SO 4 , is an important and widely used oxidant in organic synthesis for a variety of transformations such as oxidation of alkenes to epoxides, 9 thioethers to sulfones, 10 aldehydes to carboxylic acids, 11 and tertiary amines to amine oxides. 12 In addition, oxone® is also known to promote bromination, 13 hydroxybromination, 14 and ...
