Synthesis and Structure of a Mononuclear Palladium(I) Complex and Its Catalytic Activity for Suzuki–Miyaura Cross-Coupling Reaction by Immobilizing on SBA-15
Abstract
Treatment of palladium precursor Pd(PPh3)Cl2 with equivalent arylfluorodithiophosphato ligand [PPh4][(4-EtO-C6H4)FPS2] in chloroform at reflux resulted in a mononuclear palladium(I)–sulfur complex cis-[Pd(PPh3)2{κ2-S,S′-(4-EtO-C6H4)FPS2}]. This complex was characterized by UV-Vis and IR spectroscopic analysis, thermogravimetric analysis, and XPS analysis, and its molecular structure has been established by single-crystal X-ray diffraction. SBA-15, as a mesoporous material, was selected as a mesoporous silica substrate to further form a homogeneous catalyst, Pd@SBA-15, which has been characterized by IR spectroscopy, electron microscope and N2 adsorption–desorption test. In addition, the catalytic activity of Pd@SBA-15 for the Suzuki–Miyaura cross-coupling reaction was also investigated.
