Abstract Advanced lithium‐ion batteries (LIBs) are crucial to portable devices and electric vehicles. However, it is still challenging further develop the current anodic materials such as graphite due intrinsic limited capacity sluggish Li‐ion diffusion. Indium nitride (InN), which a new type of material with low redox potential (<0.7 V vs Li/Li + ) narrow bandgap (0.69 eV), may serve high‐energy density anode for LIBs. Here, growth 1D single crystalline InN nanowires reported on Au‐decorated carbon fibers (InN/Au‐CFs) via chemical vapor deposition, possessing high aspect ratio 400. The binder‐free Au‐CFs conductivity can provide abundant sites enhance binding force dense nanowires, displaying shortened Li ion diffusion paths, structural stability, fast kinetics. InN/Au‐CFs offer stable high‐rate delithiation/lithiation without achieve remarkable 632.5 mAh g −1 at 0.1 A after 450 cycles 416 rate 30 . battery anodes shall hold substantial promise fulfilling superior long‐term cycling performance capability advanced

Cheminformatics-based machine learning (ML) has been employed to determine optimal reaction conditions, including catalyst structures, in the field of synthetic chemistry. However, such ML-focused strategies have remained largely unexplored context catalytic molecular transformations using Lewis-acidic main-group elements, probably due absence a candidate library and effective guidelines (parameters) for prediction activity elements.

Abstract A strategy for modulating the Lewis acidity of triarylboranes is proposed based on concept remote back strain. Steric repulsion and noncovalent interactions, both generated between aryl meta-substituents triarylboranes, are found to be critical determining strength Applying this concept, we synthesized B[2,6-F2-3,5-(TMS)2-C6H]3 liquid B[2,6-F2-3,5-(allyl)2-C6H]3 demonstrated their superior catalytic activity hydrogenation quinoline relative B(C6F5)3 or B(2,6-F2C6H3)3. Moreover, established first example by using in presence a gaseous 1:1:1 molar mixture H2, CO, CO2.

Abstract This Short Review summarizes the synthesis and applications of triarylboranes (BAr3), including both homoleptic heteroleptic species, with a focus on modification their electronic structural properties via introduction meta-substituents respect to B atoms Ar groups. approach constitutes complementary alternative conventional strategies for design BAr3, which are usually based ortho- and/or para-substituents. An initial analysis revealed that CH3 F most common in hitherto reported BAr3 (apart from H atom). Thus, an extensive exploration other substituents, e.g., heavier halogens, longer or functionalized alkyl groups, aryl will increase our knowledge structure reactivity eventually lead range new applications. 1 Introduction 2 Scope this 2.1 The Electronic Steric Influence meta-Substituents 2.2 Molecular Transformations Mediated by meta-Substituted Boranes 2.3 Other Examples meta-Functionalization 3 Conclusions Perspectives

An isostructural series of boron/phosphorus Lewis pairs was systematically investigated. The association constants the were determined at variable temperatures, enabling extraction thermodynamic parameters. stabilization adduct increased with increasing size dispersion energy donor groups, although and acceptor properties remained largely unchanged. This data utilized to challenge state-of-the-art quantum chemical methods, which finally led an enhanced workflow for determination thermochemical weakly bound within accuracy 0.6 1.0 kcal mol-1 computed free energies.

Abstract Utilization of chiral frustrated Lewis pairs as catalysts in enantioselective hydrogenation unsaturated molecules represents a promising approach asymmetric synthesis. In our effort to improve current understanding the factors governing stereoselectivity these catalytic processes, herein we examined mechanism direct aromatic enamines catalyzed by binaphthyl–based amino–borane. Our computational analysis reveals that only one particular conformer key borohydride reaction intermediate can be regarded reactive form this species. This has well–defined propeller shape, which induces facial selectivity hydride transfer pro–chiral iminium intermediates. The chirality is generated axially binaphthyl scaffold amino–borane catalyst through stabilizing π‐π stacking interactions. new insight readily used interpret high degree stereoinduction observed for reactions. We expect concept relay could further exploited design endeavors.

The industrial production of methanol through CO hydrogenation using the Cu/ZnO/Al2O3 catalyst requires harsh conditions, and development new catalysts with low operating temperatures is highly desirable. In this study, organic biomimetic FLP good tolerance to poison are theoretically designed. base-free catalytic reaction contains 1,1-addition into a formic acid intermediate methanol. Low-energy spans (25.6, 22.1, 20.6 kcal/mol) achieved, indicating that can be hydrogenated at temperatures. extended aromatization–dearomatization effect involving multiple rings proposed effectively facilitate rate-determining step, activation model for catalysts.
