Green synthesis and characterization of palladium nanoparticles supported on zeolite Y by sonochemical method, powerful and efficient catalyst for Suzuki‐Miyaura coupling of aryl halides with phenylboronic acid

Abstract

In this paper, we report effective, useful and environmental compatible ultrasound method for the synthesis of zeolite–Y. Then, the prepared product was composed with palladium nanoparticles by sonication treatment. The prepared zeolite Y–Pd nanoparticles was used as catalyst in Suzuki‐Miyaura coupling of aryl halides (Ar‐X, X = I, Br, Cl, F) with phenylboronic acid. Based on our studies, the prepared zeolite Y‐Palladium nanoparticles revealed a high catalytic performance in Suzuki‐Miyaura coupling reaction so that aryl fluoride can even react with phenylboronic acid by utilizing this catalyst. The advantages of the use of this catalyst in Suzuki‐Miyaura coupling reaction are green solvent, short reaction time, high yields, ligandless and recyclable. Structure and morphology of the synthesized zeolite‐Y and zeolite‐Y‐Palladium nanoparticles were characterized by FT‐IR (Fourier transform infrared), XRD (X‐ray diffraction), SEM (Scanning electron microscopy), TEM (Transmission electron microscopy), EDX (Energy dispersive analysis of X‐ray), BET (Brunauer Emmett Teller) and ICP‐MS (Inductively coupled plasma mass spectrometry).
