MOFs are porous materials with a large pore aperture, crystalline structure, low density, and thermal stability that can store molecules that are active homogenous catalysts. The MOFs are converted into heterogeneous catalysts as a result of this storage. This type of catalyst is easier to separate and can be reused multiple times. Benzylic borylation can also be used as an intermediate between carbon-carbon and carbon-heteroatom bonds. NU-1000, a zirconium-based MOF, is employed to host "NiP3SiH" and “NiP3GeH”, two organometallic complexes that are active homogeneous catalysts. The generated catalysts, [Ni-1]@NU-1000 and [Ni-2]@NU-1000 allow the benzylic borylation reaction to take place in one step and can be easily removed and reused after the reaction occurs. To measure the reactions, 1H NMR and GC-MS are used to monitor them.
