IR spectroscopy of isolated metal-organic complexes of biocatalytic interest: Evidence for coordination number four for Zn2+(imidazole)(4)

The characterization of the interactions of Zn2+ ions with imidazole ligands is vital for understanding the function of a plethora of zinc enzymes at the molecular level. The infrared multiple photon dissociation (IRMPD) spectrum of mass selected Zn2+(imid ...

Kinetics of the solvent-free hydrogenation of 2-methyl-3-butyn-2-ol over a structured Pd-based catalyst

Albert Renken, Lioubov Kiwi, Rocio Micaela Crespo Quesada, Martin Grasemann

The solvent-free selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) was studied over a Pd/ZnO structured catalyst and compared to its behavior in water-assisted conditions. The catalytic behavior was correlated with the s ...

Palladium-catalyzed domino N-arylation/carbopalladation/C-H functionalization: three-component synthesis of 3-(diarylmethylene)oxindoles

Jieping Zhu

A palladium-catalyzed 3-component synthesis of 3-(diarylmethylene)indolin-2-ones was developed. A sequence of intermol. N-arylation/intermol. carbopalladation/C-H activation/C-C bond formation was realized in a 1-pot fashion allowing the construction of 1 ...

Synthesis of new aminophosphine complexes and their catalytic activities in C-C coupling reactions

Rosario Scopelliti, Zhaofu Fei, Wee Han Ang

Two new aminophosphines, benzyl-N(Ph2P)(2) and 2-picolyl-N(Ph2P)(2), have been synthesized. Oxidation of the aminophosphines with either hydrogen peroxide, elemental sulfur and selenium gave the corresponding oxides, sulfides and selenides benzyl-N(Ph2P=E) ...

Novel catalytic applications of carbon nanofibers on sintered metal fibers filters as structured supports

Marina Ruta

Supported metal catalysts are important from both an industrial and a scientific point of view. They are used, amongst others, in large-scale processes such as catalytic reforming, hydrotreating, polymerization reactions and hydrogenations. Often, these ca ...

Development of nitrile-functionalized ionic liquids for C-C coupling reactions: implication of carbene and nanoparticle catalysts

Paul Joseph Dyson, Zhaofu Fei, Wee Han Ang, Dongbin Zhao, Cinzia Chiappe

A series of nitrile-functionalized imidazolium salts (many of which are liquid at room temperature) have been prepared. The reactivity of these salts with PdCl2 has been studied, resulting in salts containing a tetrachloropalladate dianion or co ...

Photocatalytic Discoloration of Organic Compounds on Outdoor Building Cement Panels Modified by Photoactive Coatings

César Pulgarin, Victor Sarria

Cement based Eternit plates modified by TiO2/SiO2 surface layers acquired self-cleaning properties. The TiO2/SiO2 coating was transparent indicating that the small TiO2 (rutile) crystals cause no significant scattering. The parameters related to the compos ...
