Gold-Catalyzed Alkynylation: Acetylene-Transfer instead of Functionalization

Over the last fifteen years, gold has been raised from the status of an inert noble metal to one of the most-often-used catalysts in synthetic chemistry. The functionalization of the triple bond of alkynes has been especially successful in this respect. In ...

Chemoselective hydrogenation of nitroarenes: Boosting nanoparticle efficiency by confinement within highly porous polymeric framework

Lioubov Kiwi, Fernando Cardenas Lizana, Charline Berguerand

We report for the first time 99.9% yield of aminocompounds and high TOFs (up to 61 s(-1)) in the liquid-phase hydrogenation of several para-substituted (-OH, -OCH3, -CH3, -H, -Br, -Cl, -COOH and -NO2) nitroaromatics over quasi-monodispersed (ca. 3.3 nm fro ...

Selective Gas Phase Hydrogenation of

Lioubov Kiwi, Fernando Cardenas Lizana, Rocio Micaela Crespo Quesada, Xiaodong Wang

The gas phase (1 atm, 453 K) hydrogenation of p-chloronitrobenzene (p-CNB) over a series of laboratory-synthesized and commercial Pd (1-10% wt) supported on activated carbon (AC) and non-reducible (SiO2 and Al2O3) and reducible (ZnO) oxides has been examin ...

Activation of a C(sp3)H Bond by a Transient s-Alkylpalladium(II) Complex: Synthesis of Spirooxindoles Through a Palladium-Catalyzed Domino Carbopalladation/C(sp3)C(sp3) Bond-Forming Process

Jieping Zhu

Heck shortens the distance. Palladium-catalyzed activation of C(sp3)-H bond by a σ-alkyl Pd(II) complex generated in situ from a remote arylhalide function is developed. The novel domino carbopalladation/C(sp3)-C(sp3) bond forming process allowed a rapid a ...

Fano-resonant Asymmetric Metamaterials for Sensing and Vibrational Fingerprinting of Protein Monolayers

Hatice Altug

Precise information about the structure of protein monolayers (thickness, bond orientation, dipole strength) can be obtained using difference-reflectivity spectroscopy of functionalized Fano-resonant asymmetric metamaterials. Experimental results for pepti ...

Highly selective rhodium catalyzed domino C-H activation/cyclizations

Nicolai Cramer, Duc Tran Ngoc

The direct functionalization of carbon-hydrogen bonds is an emerging tool to establish more sustainable and efficient synthetic methods. We present its implementation in a cascade reaction that provides a rapid assembly of functionalized indanylamines from ...

Electronic properties and atomic structure of graphene oxide membranes

Klaus Kern, Daniela Pacilè, Marko Burghard, Ravi Shankar Sundaram

We have performed a near-edge X-ray absorption fine-structure (NEXAFS) and a transmission electron microscopy (TEM) investigation of freely suspended graphene oxide (GO) sheets. We utilized a photoemission electron microscope to identify GO membranes and t ...

A Well-Defined Ni Pincer Catalyst for Cross Coupling of Non-Activated Alkyl Halides and Direct C-H Alkylation

Oleg Vechorkin

Carbon-carbon bond forming reactions are among the most important and useful methods for organic synthesis. During the last years, significant progress has been made in this field. Whereas many catalysts were developed for the coupling of aryl, alkenyl, an ...

Defect levels of carbon-related defects at the SiC/SiO2 interface from hybrid functionals

Alfredo Pasquarello, Peter Broqvist, Audrius Alkauskas, Fabien Devynck

We investigate carbon single-atom and pair defects at the SiC/SiO2 interface as candidate defects for the density of defect states in the SiC band gap. In order to accurately describe the electronic defect levels with respect to the SiC band edges, we use ...
