Cover Picture: Amine Grafting on Coordinatively Unsaturated Metal Centers of MOFs: Consequences for Catalysis and Metal Encapsulation (Angew. Chem. Int. Ed. 22/2008)
Site-selective functionalization ... of coordinatively unsaturated sites in MIL-101, Cr3(F,OH)(H2O)2O[(O2C)-C6H4-(CO2)]3·n H2O (n≈25), is described by J.-S. Chang, G. Férey et al. in their Communication on page 4144 ff. After dehydration of MIL-101, grafting with amine molecules followed by noble-metal encapsulation leads to metal–organic frameworks having high catalytic activity in the Knoevenagel condensation and the Heck coupling reaction.
