Abstract
A novel metal-organic framework consisting of supported triazine-aminopyridine (MIL-101(Cr)-NH-TA-AP) was fabricated by post-synthetic modifications of MIL-101(Cr)-NH2. Utilizing the excellent chelating ability of triazine-aminopyridine, Cu ions are immobilized over the host matrix (MIL-101(Cr)-NH-TA-AP/Cu). Subsequently the material has been catalytically employed in the cross-coupling of aryl halides with ammonium acetate (NH4OAc), as the amine source in the presence of cesium carbonate (Cs2CO3) towards the synthesis of diverse aniline derivatives. Some advantages of the synthesized catalyst are high catalytic activity, mild conditions, high thermal stability, and reusability. Moreover, this porous multifunctional nanomaterial can be used as a new support to immobilize other metals in different catalytic reactions.
