Abstract

In this research, Pd@Cu-MOF is used as a reusable heterogeneous catalyst to develop a unique approach for the synthesis of diaryl ketones via CH activation reaction of aryl aldehydes and arylhalides with good yield. Pd nanoparticles encapsulated in the metal-organic framework (Pd@Cu2(BDC)2DABCO) and the structure of the catalyst was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), BET, transmission electron microscopy (TEM). The catalyst was recycled and reused four times without significant loss of activity. A plausible mechanism is provided and the chemical structures of the synthesized compounds were confirmed by comparison of their melting points with literature and 1HNMR spectra.
