Unprecedented scope, reactivity, and stability are displayed by a new catalyst system. This was demonstrated with general and efficient syntheses of sterically hindered (hetero)biaryls (see examples shown), mild coupling reactions of alkyl boron derivatives, and rapid coupling reactions of aryl chlorides at room temperature.

A Cu complex based on 2,2′-bipyrimidine ([CuBpm·2H2O]n) as a recyclable metal-organic framework (MOF) was used for the synthesis of biaryl derivatives by the Suzuki coupling reaction. The Suzuki reaction was performed with mixing of aryl halides with arylboronic acids in DMSO. The prepared catalyst was characterized by FT-IR, XRD, SEM, EDX, BET, BJH and ICP-AES analysis. [CuBpm·2H2O]n as catalyst demonstrated good to excellent yields for Suzuki reaction in comparison with other catalysts. The catalyst was recovered by a simple filtration and retained its activity even after several cycles.

The Magnetite@MCM-41@NHC@Pd catalyst was obtained with Pd metal bound to the NHC ligand anchored to the surface of Fe3O4@MCM-41. It was characterized by Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), energy disperse X-ray analysis (EDX), thermogravimetric analysis (TGA), differential thermal analysis (DTA), and scanning electron microscopy (SEM). The amount of Pd in the Magnetite@MCM-41@NHC@Pd was measure by inductively coupled plasma–optical emission spectroscopy (ICP-OES) analysis. The catalytic activity of Magnetite@MCM-41@NHC@Pd heterogeneous catalyst done on Suzuki–Miyaura reactions of aryl halides with different substituted arylboronic acid derivatives. All coupling reactions afforded excellent yields and up to 408404 Turnover Frequency (TOF) h?1 in the presence of 2 mg of Magnetite@MCM-41@NHC@Pd catalyst (0.0564 mmol g?1, 0.01127 mmol% Pd) at room temperature in 2-propanol/H2O (1:2). Moreover, Magnetite@MCM-41@NHC@Pd catalyst was recover by applying the magnet and reused for another reaction. The catalyst showed excellent structural and chemical stability and reused ten times without a substantial loss in its catalytic performance.
