A readily accessible catalyst system consisting of Pd/charcoal in combination with bismuth(III) nitrate and tellurium metal enables an efficient aerobic oxidative methyl esterification of primary alcohols, exhibits a broad substrate scope, and is effective with both activated and unactivated alcohols bearing diverse functional groups. The Bi and Te additives significantly increase the reaction rate, selectivity, and overall product yields.
