Abstract
Screening of simple binary and ternary admixtures of Pd/charcoal in combination with one or two metal and/or metalloid components as the catalyst for aerobic oxidative methyl esterification of primary alcohols revealed two very effective catalyst compositions. One was used in batch aerobic oxidation reactions, whereas the other achieved nearly 60 000 turnovers in a continuous-flow packed-bed reactor with no apparent loss of catalytic activity.
