IBX-mediated oxidation of primary alcohols and aldehydes to form carboxylic acids

Abstract

Under mild conditions and without the use of toxic metals, the oxidation of primary alcohols and aldehydes to the corresponding carboxylic acids with 1-hydroxy-1,2-benziodoxole-3(1H)-one-1-oxide (IBX) proceeds in the presence of 1-hydroxypyridine or N-hydroxysuccinimide (see scheme). The reaction tolerates a wide variety of functional groups.
