A porous metal-organic framework as active catalyst for multiple C-N/C-C bond formation reactions

A 3D porous metal-organic framework {[Cu(4-tba)(2)](solvent)}(n) (1.S) is assembled via 4-(1H-1,2,4-triazol-1-yl)benzoic acid (Htba) and Cu(II) nodes, which shows the [2 + 2] rota-translational interpenetrating network. Interestingly, 1 displays high CO2 adsorption selectivity over CH4/H-2/O-2/Ar/N-2 gases, and acts an efficient catalyst precursor in some C-N/C-C bond formation reactions, including Chan-Lam coupling reaction of phenylboronic acid with imidazole, Suzuki-Miyoura coupling reaction of phenylboronic acids with aryl halides, and Heck coupling reaction of styrene with aryl halides.
