Boronic acid catalyst shuttle : In general, recovering homogeneous catalysts at the end of a chemical reaction is not easy. Easily recoverable homogeneous catalysts were developed for the dehydrative condensation reaction between carboxylic acids and amines to give amides: resin‐bound boronates, and complexes between a boronic acid and DMAP or DMAP N ‐oxide. Soluble active boronic acids are released from these solids, and work as homogeneous catalysts during the reaction, and are recovered by decantation after the reaction completion. Their behavior resembles a space shuttle. More information can be found in the Communication by Kazuaki Ishihara et al. on page 1191 in Issue 9, 2017 (DOI: 10.1002/ajoc.201700194).
