Cycloalkane Oxidation Catalyzed by Copper-based Catalysts with H2O2 under Mild Conditions

Copper-catalyzed cycloalkane oxidation using H2O2 as an oxidant was investigated under mild conditions. The copper catalysts studied in this work ranged from commercially-available copper(II) salts to copper(II) complexes containing polypyridyl ligands. Va ...

Mechanistic classification and benchmarking of polyolefin depolymerization over silica-alumina-based catalysts

Paul Joseph Dyson, Mounir Driss Mensi, Felix Daniel Bobbink, Antoine Philippe Van Muyden, Wei-Tse Lee, Jed Russell Carullo

Carbon-carbon bond cleavage mechanisms play a key role in the selective deconstruction of alkanes and polyolefins. Here, we show that the product distribution, which encompasses carbon range and formation of unsaturated and isomerization products, serves a ...

Site-selective Synthesis of -[70]PCBM-like Fullerenes: Efficient Application in Perovskite Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jiyoun Seo, Seckin Akin

We report on the site-selective synthesis of PCBM-like [70]fullerene site-isomers, where the elusive -site-isomers are, for the first time, the major product in a (cyclo)addition chemical reaction involving [70]fullerene. The reaction involves an straightf ...

Nickel pincer model of the active site of lactate racemase involves ligand participation in hydride transfer

Rosario Scopelliti, Xile Hu, Matthew Wodrich, Tao Xu

Pincer complexes are widely applied in homogeneous catalysis. However, only very recently has the first pincer complex been discovered in the active site of a metalloenzyme, namely, lactate racemase. Here, we report a synthetic model of the active site of ...

Natural inspirations for metal–ligand cooperative catalysis

Xile Hu, Matthew Wodrich

In conventional homogeneous catalysis, supporting ligands act as spectators that do not interact directly with substrates. However, in metal–ligand cooperative catalysis, ligands are involved in facilitating reaction pathways that would be less favourable ...

Spectroscopy of 3, 4, 9, 10-perylenetetracarboxylic dianhydride (PTCDA) attached to rare gas samples: Clusters vs. bulk matrices. II. Fluorescence emission spectroscopy

Wolfgang Harbich, Alexandre Rydlo, Stefan Minniberger, Matthieu Dvorak

The interaction between 3, 4, 9, 10-perylenetetracarboxylic dianhydride (PTCDA) molecules and solid rare gas samples is studied by means of fluorescence emission spectroscopy. Laser-excited PTCDA-doped large argon, neon, and para-hydrogen clusters along wi ...

Improving Protein Pharmacokinetics by Engineering Erythrocyte Affinity

Jeffrey Alan Hubbell, Stephane Kontos

Poor pharmacokinetic profiles are often the underlying reason for the failure of novel protein drugs to reach clinical translation. Current passive half-life improvement methods focus on increasing the apparent hydrodynamic radius of the drug. We sought to ...

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 ...

A Chemoenzymatic Approach for the Synthesis of Unnatural Disaccharides Containing D-Galacto- or D-Fucofuranosides

Ronan Euzen

Unusual diglycosides composed of D-hexofuranosyl entities were prepared by a chemoenzymatic route using the -L-arabinofuranosidase, AbfD3. The required, unprotected monosaccharidic donors were first prepared according to multi-step syntheses. Since one goa ...
