 Triheterometallic Lanthanide Complexes Prepared from Kinetically Inert Lanthanide Building Blocks (Eur. J. Inorg. Chem. /2017)

The cover picture shows the antenna effect, in which a chromophore excited state can sensitize the lanthanide-centered emission by energy transfer via a Dexter mechanism. The dimmer terbium and ytterbium ions show that light hitting the antenna cannot sensitize the emission of these, while the bright red europium can be sensitized by the antenna. In our paper we show that sensitized lanthanide luminescence can only occur if the antenna and the lanthanide ion can collide, and that collisions can be prevented by steric congestion. Details are discussed in the article by T. J. Sørensen, S. Faulkner et al. on page -- ff (DOI: 10.1002/ejic.201700027).

 Synthesis and Structural Studies of Three‐Dimensional Supramolecular Motifs Derived from Neutral and Cationic Zinc Alkanesulfonates (Eur. J. Inorg. Chem. /2017)

The cover picture shows the potential of zincate anions bearing weakly coordinating alkanesulfonate groups as synthons for three-dimensional supramolecular assemblies. Depicted in the background is the architecture of Howrah Bridge, Kolkata, India, which has been built on two end-to-end supports. It reflects the concept of simple coordination complexes as building units to construct supramolecular three-dimensional frameworks by cooperative noncovalent interactions. Details are discussed in the article by R. Shankar et al. on page -- ff (DOI: 10.1002/ejic.201601320).

Synthesis and Characterization of 1,2-Azaborine-Containing Phosphine Ligands: A Comparative Electronic Structure Analysis

4 aprile, 2017 - 00:00

 A Comparative Electronic Structure Analysis

We describe the electronic structure of BN isosteres of two triarylphosphines, tri-o-tolylphosphine and diphenyl-o-tolylphosphine. UV-photoelectron spectroscopy of the free tri-o-tolylphosphine ligand pair (BN vs. CC) and the Tolman electronic parameters of the Mo(CO)4L2 complexes of the diphenyl-o-tolylphosphine pair demonstrate that the BN-containing phosphines are stronger electron donors.

Copper-Catalyzed Alkoxycarbonylation of Alkanes with Alcohols

4 aprile, 2017 - 00:00

Copper‐Catalyzed Alkoxycarbonylation of Alkanes with Alcohols

The Back Cover picture shows and ancient ding, which has been used as food container in China since the Chalcolithic period. It is made from copper, and later on it has become a symbol of power. The term “inquiring of the ding” (Chinese: image, pinyin: wèn di&#x1CE;ng) is often used interchangeably with the quest for power. In our work, we succeeded in the copper-catalyzed alkoxycarbonylation of alkanes. It is a challenging transformation, and succeeding in this reaction is a kind of “wen ding”. Esters were produced from the copper-made ding, representing the good smell of food and also delivering best wishes (A harvest year!). More details can be found in the Communication by Li et al. (DOI: 10.1002/cssc.201601587).

Nitrogen Fixation by Gliding Arc Plasma: Better Insight by Chemical Kinetics Modelling

4 aprile, 2017 - 00:00

 Better Insight by Chemical Kinetics Modelling

Fixation models: Nitrogen fixation is gaining increasing interest owing to its essential role in the nitrogen cycle of the biosphere. Gliding arc plasma has great potential for this purpose, however, the understanding of the underlying mechanisms is very limited. This work presents an extensive study elucidating the plasma chemistry by a combination of experiments and computations to provide the necessary insights for improving gliding arc based NOx synthesis.

Elongated and Shortened Peptidomimetic Inhibitors of the Proprotein Convertase Furin

4 aprile, 2017 - 00:00

Elongated and Shortened Peptidomimetic Inhibitors of the Proprotein Convertase Furin

Elongated and shortened inhibitors of the proprotein convertase furin were developed, based on the lead structure phenylacetyl-Arg-Val-Arg-4-amidinobenzylamide. The best compounds inhibit the propagation of chikungunya virus and Semliki Forest virus in the micromolar range. Furthermore, the activation of diphtheria toxin was found to be inhibited in the presence of selected compounds.

A Case Study on the Influence of Substitutes on Interlayer Stacking of 2D Covalent Organic Frameworks

Inclined stacking of covalent organic framework monolayers has been experimentally confirmed for the first time. The unprecedented stacking manner was realized through the condensation of 1,4-diaminobenzene or benzidine with a truxene-based building block in which six methyl groups were fixed out-of-plane of the truxene core.

 Insights from Large‐Scale Quantum Mechanics Analysis of Experimentally Derived Models

Shaping up! Supramolecular interactions in large-scale models of parallel and antiparallel G-quadruplexes were analyzed. Quantum chemical topology and energy decomposition approaches indicate distinct networks of interactions that slightly favor the parallel arrangement (see figure).

 A Systematic Study of the Na+‐Complex Stability and the Na+/K+ Selectivity in Acetonitrile and Water

Probing for ions: We report on the development of Na+-selective fluorescent probes, which consist of 15-membered crown ether ionophores and of coumarin or &#x3C0;-extended coumarin derivatives, as fluorophores. These fluoroionophores show different Na+-complex stabilities and Na+/K+ selectivities in acetonitrile and water.

Hydrogen‐Atom Transfer (HAT) Initiated by Intramolecular Ligand–Metal Electron Transfer

CuII complexes with redox-active urea azine ligands undergo ligand–metal electron transfer reactions in solutions. The resulting radical monocationic urea azines with nitrogen-centered radical react further via HAT to carbon-centered radicals, and finally to diamagnetic products.

N-Heterocyclic Carbene Based Tri-organyl-Zn–Alkyl Cations: Synthesis, Structures, and Use in CO<sub>2</sub> Functionalization

4 aprile, 2017 - 00:00

 Synthesis, Structures, and Use in CO2 Functionalization

Set in its ways: Tri-organyl ZnII cations, [(NHC)2Zn-Me]+, were synthesized and structurally characterized to unveil a coordination chemistry strongly dependent on sterics. Severe steric hindrance may induce a normal-to-abnormal N-heterocyclic carbene (NHC) isomerization. Cation [(aIDipp)(nIDipp)Zn-Me]+ (IDipp=1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) inserts CO2 into its Zn–alkyl bond at room temperature and catalyzes CO2 hydrosilylation (see scheme).
