摘要

It has been found that aromatic aldehydes with electron-withdrawing as well as electron- donating substituents are oxidized to arenecarboxylic acids using tert-butyl hydroperoxide in the presence of ebselen (2-phenylbenzisoselenazol-3 (2H)-one) as a catalyst. The reaction is highly chemoselective and formation of phenols, being the products of competitive Baeyer– Villiger rearrangement, is marginal. It has been assumed that this rearrangement is ...
