Abstract

Abstract : Hemicucurbiturils provide a first example of supramolecular templating and selective formation of differently sized ring molecules in a solvent‐free, mechanochemical reaction environment. In their Communication on page 6230 ff., T. Friščić, R. Aav, and co‐workers show how mechanochemically prepared oligomers spontaneously and selectively reorganize in the solid state into six‐ or eight‐membered macrocycles, depending on the chosen anionic template.
