Cu-2(BDC)(2)(BPY)-MOF: an efficient and reusable heterogeneous catalyst for the aerobic Chan-Lam coupling prepared via ball-milling strategy

Nanoporous Cu-2(BDC)(2)(BPY)-MOF was used as efficient and reusable heterogeneous catalyst to effect the aerobic cross-coupling of aromatic amines and phenyl boronic acid (Chan-Lam coupling). Ball-milling strategy was utilized for the first as a powerful green and energy-efficient method for the synthesis of this nanoporous metal-organic framework. Certain ratio of metal ion and organic linkers were held to improve the quality of nanostructures. Cu-2(BDC)(2)(BPY) were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Brunauer-Emmett-Teller (BET) surface area analysis.
