摘要

Abstract Various alkyl aryl ketones, dialkyl ketones, and cycloheptanone were efficiently converted into the corresponding α-tosyloxy ketones in good yields by using Oxone® and p- toluenesulfonic acid monohydrate in the presence of p-iodotoluene in acetonitrile. 4- Methoxyacetophenone and 2-acetylthiophene bearing an electron-rich aromatic group could be also converted into the corresponding α-tosyloxyketones smoothly in good yields ...
