Summary: The molybdenum and tungsten oxo 2-adamantylidene complexes were prepared by adding 2-methylene- or 2-ethylideneadamantane to neophylidene or neopentylidene complexes. The tungsten complex 2(w) is a thermally stable dimer with unsymmetrically bridging oxo ligands, while the molybdenum complex 2(Mo) is a stable monomer. These complexes are reactive olefin metathesis initiators with dimers 5(Mo) and 5(w) being relatively poor initiators.

Summary: Four new Mo(NAr)(CR1R2)(OSiPh3)(2) complexes and three new Mo(NAr)(olefin)(OSiPh3)(2) complexes were prepared. The syntheses of other olefin complexes were complicated by isomerization reactions. Addition of [(Et2O)(2)H][B(C6F5)(4)] to the alkylidene complexes generated cationic alkyl complexes which can be deprotonated to form disubstituted alkylidene complexes.

Summary: We have developed a method for olefination of oximes to produce cyclic alkene products. This approach involves the formation of Ru alkylidenes in situ from [RuCl2(p-cymene)]2 and 3,3-diphenylcyclopropene as carbene precursors. The desired functionalized alkenes were obtained with yields up to 58%. Compared to previous strategies, this method eliminates the use of commercially available Ru alkylidenes, reducing overall costs and providing mechanistic insights for future catalytic variants of the reaction.

Summary: In this study, a new method for the synthesis of reactive tantalum species was developed by employing a novel NHC scaffold to prevent dimer formation during reductive hydrogenation. The isolated hydrido-tantalum alkyl exhibited bidirectional reactivity, undergoing either alpha-elimination or reductive alkane elimination upon heating. This study also demonstrated the formation of a cyclometalated tantalum hydride through oxidative C-H activation and revealed its subsequent reactivity with alkenes and alkynes, including a unique hydrogen shift reaction.

Summary: We used nuclear magnetic resonance approaches to determine Li-ion mobility pathways and quantify Li-ion jump rates in Li3AlS3 and Li4.3AlS3.3Cl0.7. In Li3AlS3, there are both mobile and immobile Li ions, with the latter limiting long-range translational ion diffusion. In Li4.3AlS3.3Cl0.7, a single type of fast-moving ion is present, explaining the higher conductivity of this phase.

Summary: Single-atom catalysts (SACs) have shown improved electrocatalytic performance in various industrially relevant reactions, including oxygen evolution reaction (OER). However, the stability of SACs has received little attention in the literature. In this study, we evaluate the stability of Ir SAC and highly dispersed Ru catalysts supported by indium doped tin oxide (ITO) using online inductively coupled plasma mass spectrometry setup (online ICP-MS). We find that these catalysts exhibit high activity but lower stability, and propose that the change in OER mechanism from adsorbate evolution mechanism (AEM) to lattice oxygen mechanism (LOM) with participation of the support contributes to their lower stability.

Summary: The study presents an expert-curated dataset of lithium ion conductors and their associated conductivities. The dataset contains 820 entries collected from 214 sources, including chemical composition, structural label, and ionic conductivity at specific temperatures. Unsupervised machine learning and the Element Movers Distance were used to analyze the materials in the context of compounds from an inorganic crystal structure database. A CrabNet-based classifier was trained using this dataset to estimate the ionic conductivity of chemical compositions. This classifier serves as a practical tool for experimentalists in prioritizing candidates for further investigation as lithium ion conductors.

Summary: This article investigated the relationship between olefin metathesis activity of silica-supported molybdenum oxides and metal loading and preparation conditions. Results showed that similar catalysts with different compositions exhibit different reaction properties. The catalyst synthesized via surface organometallic chemistry showed better performance than a classical catalyst with similar metal loading. Solid-state Mo-95 NMR analysis revealed four distinct surface Mo dioxo sites with different distributions depending on the catalyst preparation methods. The intensity of a specific deshielded Mo-95 NMR signal was linked to reducibility and catalytic activity.

Summary: Generating or retaining slow magnetic relaxation in surface-immobilized single-molecule magnets (SMMs) from molecular precursors is a challenging task. However, a material with SMM characteristics has been successfully generated by chemisorption of (Cp-ttt)(2)DyCl on a silica surface containing tailored Lewis acidic Al-(III) sites. Detailed studies reveal slow magnetic relaxation up to 51 K, hysteresis up to 8 K, and an effective energy barrier (U (eff)) of 449 cm(-1), the highest reported for a supported SMM.

Summary: This study investigates the active state of Au-Zn catalysts for CO2 hydrogenation to methanol. Silica-supported bimetallic Au-Zn alloys, prepared by surface organometallic chemistry (SOMC), are shown to be efficient catalysts for CO2 hydrogenation to methanol. In situ X-ray absorption spectroscopy (XAS), together with gas-switching experiments, amplifies subtle changes occurring at the surface of the catalyst. Multivariate curve resolution alternating least-squares (MCR-ALS) analysis identifies an Au-Zn alloy and reveals its reversible redox changes under reaction conditions. These findings highlight the role of alloying and dealloying in Au-based CO2 hydrogenation catalysts and the significance of reversible processes in driving reactivity.

Summary: Gold nanoparticles dispersed on mordenite efficiently catalyze the selective oxidation of methane to methanol by molecular oxygen in aqueous medium in the presence of carbon monoxide. The methanol productivity reaches 1300 mu mol g(cat) (-1) h(-1) or 280 mmol g(Au) (-1) h(-1) with 75% selectivity at 150 degrees C, outperforming most catalysts reported under comparable conditions. Both hydroxyl radicals and hydroperoxide species participate in the activation and conversion of methane, while the lower affinity of methanol on gold mainly accounts for higher methanol selectivity.

Summary: The authors identify a dynamic site renewal and decay cycle, mediated by proton transfers involving proximal BrOnsted acidic OH groups, which operates concurrently with the Chauvin cycle and could address roadblocks associated with industrial metathesis processes. This cycle can be manipulated using small quantities of promoter olefins to drastically increase steady-state propylene metathesis rates, with negligible promoter consumption, showing potential applicability to other reactions. The increase in activity and reduction of operating temperature requirements were also observed on MoOx/SiO2 catalysts, indicating the broad scope of this strategy in addressing major challenges in industrial metathesis processes.

Summary: Rh-based catalysts modified by Mn were studied for CO2 hydrogenation. The addition of Mn shifts the products from pure CH4 to a mixture of methane and oxygenates. In situ XAS confirms the presence of atomically dispersed Mn-II in the vicinity of metallic Rh nanoparticles, which induces the oxidation of Rh to form the Mn-O-Rh interface under reaction conditions. The formed interface is proposed to be key to maintaining Rh+ sites and promoting the formation of CO and alcohols.
