Summary: Bis-and tris-pyridyl borate ligands with pyridyl donor arms, a methylated boron cap, and a fluorine-lined coordination pocket have been synthesized and used in coinage metal chemistry. These ligands allowed for the isolation of group 11 metal-ethylene complexes, with gold complexes showing the largest coordination-induced upfield shifts of the ethylene 13C resonance. Solid-state structures of these complexes revealed the rare K2 coordination mode instead of the typical K3 coordination mode. Computational analyses indicated the favored K2 coordination mode and the strong interaction between gold(I) and ethylene.

Summary: This study introduces a novel chiral-at-iron catalyst and develops a more convenient synthesis method. In the new catalyst, N-(2-pyridyl)-substituted Nheterocyclic carbene (NHC) ligands coordinate around a central iron ion to generate a stereogenic metal center. The pi-acceptor properties of the modified NHCs were investigated, and the chiral-at-iron complex exhibited excellent asymmetric catalytic activity under open-flask conditions.

Summary: This study investigated the synthesis and structural characterization of six new [HgTe]-based cluster compounds derived from bis(2-pyridyl)ditellane and different mercury salts. Various techniques, including single-crystal X-ray diffraction and FT-IR spectroscopy, were used to study the compounds, and their optical properties were evaluated by solid-state UV-Vis diffuse reflectance spectroscopy. The results showed a strong dependence of the optical properties on the core structure's size and composition, with smaller core structures presenting larger energy gap values.

Summary: The zwitterionic compounds, such as pyridine-containing tellurenyl compounds, are versatile building blocks for heterometallic assemblies. Reactions of these compounds with the rhenium(V) complex result in the formation of [ReO2Cl(pyTeCl)(PPh3)(2)] and [ReO2Cl(CF(3)pyTeCl)(PPh3)(2)], which exhibit elongated Re-O bonds and Te-O contacts. The oxidation states of the metal ions are ambiguous, and DFT calculations suggest the formation of a Re(V) dioxide complex donating into an organotellurium(II) chloride.

Summary: Hydrophobic coatings inspired by the lotus effect have gained popularity for their ability to solve various problems. The sol-gel method, utilizing silica, alumina, and titania, is explored as an environmentally friendly approach to produce water-based hydrophobic coatings. This study focuses on producing water-based hydrophobic coatings for cotton and polyester fabrics using a one-step sol-gel method. The coated fabrics exhibited improved hydrophobic properties, altered surface morphologies, and lower air permeability compared to uncoated fabrics. TEOS-PDMS coating provides a promising approach for enhancing the hydrophobic and surface properties of cotton and polyester fabrics.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
