Organometallic-type reactivity of stable organoboronates for selective (hetero)arene C−H/C-halogen borylation and beyond Organometallic reagents are essential tools in both academic and industrial laboratories and the polarity separation within the carbon-metal bonds endows them with exceptional reactivities, but also imposes limitations, including air- and moisture-sensitivity, and flammability. Here, we demonstrate that stable and easily accessible benzylic (or allylic) boronate with alkali-metal alkoxide as the activator can act as reactive organometallic reagents. This strategy enables transition metal-free deprotonative C-H borylation of diverse (hetero)arenes. The polar organometallic nature of this process enables predictable and site-selective borylation by targeting the arenes's most acidic C-H bond. This approach can be coupled with Suzuki-Miyaura reaction to produce C-H arylation products. We have also applied this strategy to the dehalogenative borylation of aryl bromides and anionic polymerization of styrenes. Given the unique stability and structural diversity of organoboronates, their organometallic-type reactivities show promise as a powerful alternative to synthetic methodologies that rely on sensitive organometallic reagents.

Matching Zeolites with Metal Species for Efficient Catalysis Supported metal catalysts are essential for industrial processes like energy conversion, chemical synthesis, and pollutant removal, yet they often suffer from low activity, poor selectivity, and deactivation.Matching zeolites with metal species is an effective method for synthesizing highly efficient heterogeneous catalysts, where the zeolite crystals can not only stabilize the metal species against sintering/leaching, but also enhance the catalytic activity and product selectivity.In this mini-review, we briefly summarize recent advances in matching zeolites with metal species for efficient catalysis, highlighting the synergistic effect between zeolites and metal species to improve the catalytic performance.Multiple functions of zeolites with respect to the metal species are highlighted, including the regulation of reactant/product diffusion for increasing the catalytic activity, the control of steric adsorption of reactant for changing the product selectivity, and the modulation of dynamic structural change of metal species for enhancing the catalyst stability.Additionally, future challenges and opportunities in rational metal-zeolite catalyst design are discussed to inspire further innovations in catalytic applications.We believe that this mini-review will open up novel pathways for the widespread utilization of metal-zeolite catalysts in diverse catalytic processes.

First-principles exploration of Sc- and Y-based MXenes with halogen terminations Abstract Transition metal carbides and nitrides (MXenes) have been extensively studied owing to their compositional diversity and tunable properties, with Y- and Sc-based MXenes predicted to exhibit semiconductor behavior. While top-down synthesis of Sc- and Y-based MXenes is hindered by the lack of suitable precursors, existing crystalline stacks of multilayer Sc/Y carbides offer new strategies for achieving these MXenes. In this study, we theoretically investigated Sc- and Y-based MXenes with halogen terminations (F, Cl, Br, and I), examining their lattice structures, electronic properties, and potential applications. Multilayer structures of halogen-terminated Sc and Y MXenes were confirmed by first-principles calculations, in which the exfoliation of two-dimensional multilayers with Cl, Br, and I terminations was found to be achievable, whereas F-terminated stacks are expected to remain in multilayer structures. Semiconducting carbides, regardless of dimensionality, show promise for photocatalytic water splitting with tunable catalytic performance under different pH conditions.

Chemical hydrogen storage materials – boranes and silanes catalytic solvolysis and dehydrogenation: a mechanistic and regeneration perspective Hydrogen (H 2 ) has gained a lot of interest as an alternative energy vector, to reduce greenhouse gas emission issues caused by the fossil fuel industry. However, to make hydrogen a real energy carrier in a decarbonated economy, a secure and sustainable supply chain is needed. This approach requires notably safe storage and efficient strategies for recycling of raw materials. We discuss in this survey the state-of-the-art in the field of chemical hydrogen storage (CHS) materials, considering two possible vectors: ammonia borane and hydrosilanes. Regardless of the vector, to achieve real use, it is necessary to understand both the performance of the system and its life cycle, which relates to catalysts structure, and the activation of chemical bonds with efficient and complete catalytic cycles. We give herein an overview of hydrolysis and/or alcoholysis from metals, using coordination complexes, molecular supported catalysts or other materials, including nanocatalysts, with a focus on mechanistic information and understanding. Notably, the studies related to these two vectors can be considered somewhat complementary. Thus, the set of bibliographic report on ammonia borane is very documented in efficient catalytic systems, while its recycling remains at a very early stage. In comparison, hydrosilanes have been much less addressed specifically as a vector for hydrogen, while their reactivity at the molecular scale benefits from a relevant understanding from coordination chemistry studies. In addition, both hydrosilane polymerization and solvolysis reaction enables the release of H 2 , and produces by-products of which added value is already established. This opening the way to economical strategies where recycling can be optional. Nevertheless, the reversibility of hydrosilanes chemistry in H 2 uptake remains attractive and is another option to develop. • Ammonia borane synthesis and chemical properties. • Boranes regeneration after solvolysis – cumulative table for mechanochemistry approaches. • Catalytic hydrolysis and alcoholysis of hydrosilanes. • Catalytic dehydrogenative oligomerization of hydrosilanes. • Regeneration and reversibility of hydrosilane solvolysis products.

Supramolecular structure@MXenes for photocatalytic applications – a review Recently, supramolecules have emerged as innovative and eco-friendly options for photocatalytic applications due to their tunable porous structures and photophysical properties. However, their low thermal stability and chemical stability pose a significant challenge. To address this, combining supramolecules with more stable materials like MXenes, which have a low Fermi energy level, is a useful strategy, in which they can form heterostructures that enhance stability and improve photocatalytic activity. The synthesis process, whether through <i>in situ</i> or post-synthesis modifications, plays a crucial role in controlling the formation of both covalent and non-covalent interactions, as well as the morphology of the heterostructures. These interactions and the resulting morphology significantly influence the recombination and separation of charge carriers (electron-hole pairs), ultimately affecting the stability and recyclability of the heterostructures in photocatalytic applications. In this review, we discuss the importance of supramolecule/MXene heterostructures, detailing their synthesis and morphology, as well as the mechanisms involved in various applications.

Effects of Dopants on the Structural, Electronic, and Energetic Properties of (ZrO<sub>2</sub>)<sub>16</sub> Clusters The integration of dopants into ZrO<sub>2</sub>-based clusters provides the possibility to modulate their physicochemical properties, making small clusters promising candidates for various applications, such as catalysis. However, the synergistic interactions between doping and adsorption of single atoms into ZrO<sub>2</sub> remain poorly understood. Therefore, in this study, we investigate the influence of lanthanum (La) doping and rhodium (Rh) single-atom adsorption on the physicochemical properties of (ZrO<sub>2</sub>)<sub>16</sub> clusters using density functional theory calculations combined with data science approaches. We found that both doping and adsorption processes lead to minor local structural changes. La doping induces minimal distortions while preserving the overall stability of the cluster, as evidenced by consistent binding energy values. Rh adsorption has a preference to bind near the O-La moieties. In contrast, the electronic structure is majorly affected by Rh adsorption, by narrowing the HOMO-LUMO energy gap, and enhancing the reactivity of those modified Zr<sub>16</sub>O<sub>32</sub> clusters. Furthermore, Hirshfeld charge analysis reveals a significant charge redistribution following La doping, which is enhanced by the adsorption of a single Rh atom, resulting in localized electronic changes.
