<p> In recent years a significant progress has been made for the carboxylation of aryl and benzyl halides with CO<sub>2</sub>, becoming convenient alternatives to the use of stoichiometric amounts of well-defined metal ...
<p> The first total synthesis of the antiviral (+)-schisanwilsonene A has been completed using a fully stereoselective tandem cyclization/1,5-migration/intermolecular cyclopropanation. The key reaction sequence is catalyzed ...
A new family of salphen based complexes, viz. Zn(salphenazine)s, has been prepared and is characterized by a larger π-surface compared to previously reported Zn(salphen) complexes. The spectroscopic properties of these ...
The development of a heterogeneous one-component bifunctional catalyst system able to catalyse the conversion of carbon dioxide and oxiranes to organic cyclic carbonates at low temperature (45 oC) is reported. The bifunctional ...
<p> Stable and easily synthesized metal–organic framework MIL-88B-NH<sub>2</sub> represents an attractive support for catalysts employed in oxidation reactions, which are typically performed under relatively harsh ...
<p> Extremely slow and extremely fast new water oxidation catalysts based on the Ru–bda (bda=2,2′-bipyridine-6,6′-dicarboxylate) systems are reported with turnover frequencies in the range of 1 and 900 ...
<p> Three dinucleating Ru–Cl complexes containing the hexadentate dinucleating ligand [1,1′-(4-methyl-1H-pyrazole-3,5-diyl)bis(1-(pyridin-2-yl)ethanol)] (Hpbl) and the meridional 2,2′:6′,2&Prime ...
<p style="text-align: justify;"> A series of primary amino acid-derived polystyrene-supported organocatalysts was tested in <em>anti</em>-selective Mannich reactions. The polystyrene-immobilized threonine derivative ...
<p> We report the synthesis of a solution-processable, dodecyloxyphenyl-substituted azafullerene monoadduct (DPC59N) and its application as electron acceptor in bulk heterojunction organic solar cells (BHJ-OSCs). Due to ...
<p> In 1979, the seminal work of Wenkert set the standards for the utilization of aryl and vinyl ethers as coupling partners <em>via</em> C–O bond-cleavage. Although the topic remained dormant for almost three ...
<p> Co(II) complexes of aminotrisphenolate<br /> ((ArO)3N3−) ligands can be prepared straightforwardly in high<br /> yield. X-ray analysis reveals these complexes to comprise of two<br /> different hemispheres, ...
<p> The conversion of carbon dioxide (CO<small><sub>2</sub></small>), an abundant renewable carbon reagent, into chemicals of academic and industrial interest is of imminent importance to create a higher degree of ...
<p> High-oxidation-state decay of mononuclear complexes [RuTB(H2O)]2+ (X2+, where B = 2,2′-bpy or bpy for X = 1; B = 5,5′-F2-bpy for X = 2; B = 6,6′-F2-bpy for X = 3; T = 2,2′:6′,2″- ...
<div> A conjugated acceptor–donor–acceptor (A–π-D–π-A) with the Zn-porphyrin core and the di-cyanovinyl</div> <div> substituted thiophene (A) connected at meso positions denoted as VC62 ...
<p> Mononuclear complexes in- and out-[Ru(Cl)(trpy)(Hbpp)]+ (in-0, out-0; Hbpp is 2,2′-(1H-pyrazole-3,5-diyl)dipyridine and trpy is 2,2′:6′,2″-terpyridine) are used as starting materials for ...
<p> Metal-catalyzed reductive coupling reactions of aryl halides and (pseudo)halides with carbonyl-type compounds have undergone an impressive development within the last years. These methodologies have shown to be a ...
<p> Herein, we report the facile synthesis of an efficient roll-like carbon nitride (C3N4) photocatalyst for hydrogen production using a supramolecular complex composed of cyanuric acid, melamine, and barbituric acid as ...
<p> A broad and critical description of the state-of-the-art in water oxidation electrocatalysts for the oxygen-evolving reaction is given. Technologically relevant catalysts for energy production from earth-abundant ...
