Bismuth(III) Oxide Catalyzed Oxidation of Alcohols with tert-Butyl Hydroperox-ide. — The Bi2O3-mediated oxidation of primary and secondary alcohols (I) and (III) to carboxylic acids (II) and ketones (IV) does not depend on ligands or other additives. This mild catalytic system shows sufficient selectivity to enable the expected oxidation to take place without affecting other functionalities like phenol and amine groups, cf.(Id). Different substitution patterns at the phenyl ring do not hinder the reaction, though the reaction time is affected. The transformation of secondary alcohols (III) into ketones (IV) proceeds especially facile. — (MALIK, P.; CHAKRABORTY*, D.; Synthesis 2010, 21, 3736-3740, http://dx.doi.org/10.1055/s-0030-1258221 ; Dep.
