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).
Zeolite faujasite is widely used
as a catalyst in many industrial
catalytic applications. In this study, synthesis and characterization
of magnetic zeolite Y–palladium–nickel ferrite were
studied. First, palladium nanoparticles were combined with nickel
ferrite and then placed on zeolite Y by ultrasonic treatment. The
structure and morphology of the synthesized magnetic zeolite Y–palladium–nickel
ferrite were characterized using Fourier transform infrared, X-ray
diffraction, scanning electron microscopy, transmission electron microscopy,
energy-dispersive X-ray, vibrating sample magnetometer, and inductively
coupled plasma optical emission spectroscopy analysis. Also, we investigated
the catalytic activity of this prepared zeolite in Suzuki–Miyaura
coupling reaction between phenylboronic acid and aryl halides. Our
study shows that magnetic zeolite Y–palladium–nickel
ferrite is a suitable catalyst for Suzuki–Miyaura coupling
reaction. Short reaction time, high yield, and easy reusability are
the advantages of using this catalyst in carbon–carbon cross-coupling
reactions.
