The Rh‐catalyzed hydroformylation of aromatic‐substituted alkenes is performed in a planetary ball mill under CO/H 2 pressure. The dispersion of the substrate molecules and the Rh‐catalyst into the grinding jar is ensured by saccharides: methyl‐α‐ d ‐glucopyranoside, acyclic dextrins, or cyclodextrins (CDs, cyclic oligosaccharides). The reaction affords the exclusive formation of ...
