Clays, which are nontoxic, abundant, and cheap, are very promising supports for the design and preparation of green catalysts. In this work, the Pd\/bentonite catalyst was fabricated by a simple impregnation method using water as the medium. The catalyst was characterized by powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), transmission electron spectroscopy (TEM), X-ray photoelectron (XPS) and inductively coupled plasma atomic emission spectroscopy (ICP-AES) techniques. The performance of Pd\/bentonite in the Suzuki\u2013Miyaura reaction was studied. It was found that for aryl bromides and iodides with various electron-donating and electron-withdrawing groups such as \u2013CH_{3<\/sub><\/small>, \u2013OCH3<\/sub><\/small>, \u2013Cl, \u2013CN, \u2013F, \u2013COCH3<\/sub><\/small>\u00a0and \u2013NO2<\/sub><\/small>, the coupling reaction of substrates with arylboronic acid proceeded smoothly at low catalyst loading (Pd 0.06 mol%) under ambient temperature. The catalyst could be reused at least 7 times without any decrease in activity.<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"}
