Abstract
Abstract Crystalline mesoporous γ-Al2O3 has been successfully synthesized under high temperature hydrothermal conditions and used as an excellent support for Pd(OAc)2. The resulting γ-Al2O3–Pd showed excellent catalytic activity for Suzuki–Miyaura cross-coupling reaction. As low as 0.2 mol% loading of Pd was needed to obtain cross-coupling products in good to excellent yields in aqueous DMF under microwave irradiation. Moreover, the novel catalyst can be easily recovered by filtration and reused without any diminishing observable activity after five runs.
