Inside Back Cover: Mechanochemical Synthesis of Phosphazane-Based Frameworks (Chem. Eur. J. 47/2017).

Mechanochemistry is emerging as a powerful solvent ‐ free approach to chemical synthesis. Examples of mechanochemical methodologies in the synthesis of main ‐ group compounds are few and far between. It is shown that ball ‐ milling enables the solvent ‐ free synthesis of a range of phosphazane frameworks with a broad substrate scope, yielding new acyclic and macrocyclic species. Fast, selective and high ‐ yielding product generation from poorly soluble starting materials demonstrates the potential of mechanochemistry as a powerful alternative to solution ‐ based methods in synthetic main ‐ group chemistry.
