Fast temperature cycling of the catalytic CO oxidation using microstructure reactors

The possibility to increase the performance (productivity or selectivity) of a chemical reactor by using periodic variations of reaction parameters (e.g. reactant concentration or temperature) has been theoretically envisaged since the beginning of the 70t ...

Three-Phase Catalytic Hydrogenation of a Functionalized Alkyne: Mass Transfer and Kinetic Studies with in Situ Hydrogen Monitoring

Albert Renken, Lioubov Kiwi, Martin Grasemann

Systematic studies of mass transfer interactions with intrinsic reaction kinetics were performed for the threephase selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) over a modified Pd/CaC

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 ...

Structural and kinetic studies of induced fit in xylulose kinase from Escherichia coli

Henning Paul-Julius Stahlberg

The primary metabolic route for D-xylose, the second most abundant sugar in nature, is via the pentose phosphate pathway after a two-step or three-step conversion to xylulose-5-phosphate. Xylulose kinase (XK; EC 2.7.1.17) phosphorylates D-xylulose, the las ...

Facile, thermo-reversible cycloaddition of small molecules to a ruthenium(II) arene-diketiminate

Paul Joseph Dyson, Gabor Laurenczy, Andrew Douglas Phillips

Formation of a vacant coordination site on a Ru center permits an unusual binding of small molecules such as ethylene, acetylene, and dihydrogen, resulting in the transformation of the chelating β-diketiminate ligand to a β-diimine. These represe ...

Chiral bicyclo[3.3.0]octa-2,5-dienes as steering ligands in substrate-dependent rhodium-catalyzed 1,4-addition of arylboronic acids to enones

Nicolai Cramer

The synthesis of disubstituted chiral diene ligands (3aR,6aR)- and (3aS,6aS)-I (R1 = Ph, PhCH2) with a pentalene backbone from the corresponding bicyclo[3.3.0]octa-1,4-diones II is described. The compds. II were in turn accessible by enzymic resoln. of the ...

Switching the Mechanism of Catalyst Activation by Ionic Liquids

Paul Joseph Dyson, Corinne Daguenet

In ionic liqs. (ILs), the activation of a ruthenium(II) catalyst precursor occurs via an unexpected mechanism, which is different from the activation mechanism that takes place in water. The effectiveness of a biphasic catalytic hydrogenation reaction usin ...
