De Lucia, Nicholas A. published the artcileSilica Supported Molecular Palladium Catalyst for Selective Hydrodeoxygenation of Aromatic Compounds under Mild Conditions, SDS of cas: 140-11-4, the main research area is silica supported mol palladium catalyst arene selective hydrodeoxygenation.
The mol. complex chloro(2,2′:6′,2”-terpyridine-4′-carboxylic acid)palladium(II) chloride was synthesized and was attached to the surface of amorphous silicon dioxide to generate a mol./heterogeneous catalyst motif. This catalytic system exhibited excellent selectivity (>99%) for hydrodeoxygenation of oxygenated aromatics under mild reaction conditions. A kinetic anal. showed that this mol./heterogeneous catalyst was an order of magnitude more active than analogous homogeneous catalysts. Characterization techniques such as XRD and solid-state NMR, in conjunction with ICP-MS, indicate that the mol. catalyst is present on the surface of SiO2 and the formation of unwanted metallic Pd nanoparticles can be avoided. Computational modeling shows the catalysts can adhere to the oxide surface through a hydrogen bonding interaction, via a Coulombic attraction between the charged mol. and the oxide surface, or through covalent bonding. Postreaction anal. of the surface-modified oxide catalysts confirmed prolonged mol. integrity of the catalyst and sustained binding of the catalyst to the oxide surface when nonpolar solvents were employed for reactions. These surface-attached mol. catalysts thus were recycled through multiple catalytic reactions.
