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 BrunauerEmmett-Teller (BET) surface area analysis.

In this paper palladium nanoparticle encapsulated in mesoporous metal-organic framework Cu 2 (BDC) 2 (DABCO) (BDC=1,4-benzenedicarboxylate, DABCO= 1,4diazabicyclo[2.2.2]octane) and employed as a heterogeneous catalyst for the synthesis of biphenyl by Suzuki coupling. The Pd@MOFs offered higher catalytic activity than common Palladium salts such as Pd(OAc) 2 , PdCl 2 .

A nano mesoporous metal-organic framework Cu 2 (BDC) 2 (BPY) (BDC=1,4-benzenedicarboxylate, BPY= 4,4'-bipyridine) could be employed as a heterogeneous catalyst for the copper-catalyzed oxidative C-H/N-H coupling between simple ketones and diamines to form pyrazines. The Cu 2 (BDC) 2 (DABCO) offered higher catalytic activity than common copper salts such as CuCl, CuBr and CuI.
