The N-arylation of imidazole was also successfully accomplished by using a two-dimensional [Cu(ima)2] metal-organic framework (Cu-MOF) in MeOH at room temperature (Li et al., 2013). Several A-arylimidazoles were generated in good to excellent yields from the coupling of imidazole and arylboronic acids (six examples, 76%-92% yields). The catalyst is highly stable and can be easily reused.

By attaching hydrophobic moieties with postmodification method or generating MOFs with hydrophobic ligands, one can obtain MOFs with more hydrophobicity. Yang et al. synthesized some fluorinated metal-organic frameworks (FMOFs) in which hydrogen atoms were substituted with fluorine atoms in all ligands. These fluorinated MOFs had enhanced thermal stability...
