Post-synthetic modification of zinc metal-organic frameworks through palladium-catalysed carbon-carbon bond formation

Post-synthetic Suzuki coupling reactions have been undertaken on the halide-functionalised metal-organic frameworks (MOFs) [Zn4O(bdc-Br)3] (bdc-Br = 2-bromo-1,4-benzenedicarboxylate, IRMOF-2) and [Zn4O(bdc-I)3] (bdc-I = 2-iodo-1,4-benzenedicarboxylate). Although the bulky catalyst employed leads to relatively low conversions, the use of core-shell MOFs demonstrates that the reactions are not confined to the crystal surfaces.112
