Water-Ice Microstructures and Hydration States of Acridinium Iodide Studied by Phosphorescence Spectroscopy
Angew Chem Int Ed Engl. 2024 Apr 11:e202405314. doi: 10.1002/anie.202405314. Online ahead of print.ABSTRACTIce has been suggested to have played a significant role in the origin of life partly owing to its ability to concentrate organic molecules and promote reaction efficiency. However, the techniques for studying organic molecules in ice are absorption-based, which limits the sensitivity of measurements. Here we introduce an emission-based method to study organic molecules in water ice: the phosphorescence displays high sensitivity depending on the hydration state of an organic salt probe, acridinium iodide (ADI). The de...

Angew Chem Int Ed Engl. 2024 Apr 11:e202404679. doi: 10.1002/anie.202404679. Online ahead of print.ABSTRACTWe disclose a Ni-catalyzed cyclization/alkylmetal interception reaction in which products are readily linearized to permit regiodefined alkene dicarbofunctionalization. This method offers a convenient route to access 1,2-oxasilolane heterocycles, 3-hydroxysilanes and 4-arylalkanols with the formation of C(sp3)-C(sp3) bonds at primary and secondary alkyl carbon centers. In this reaction, a silicon-oxygen (Si-O) bond functions as a detachable linker that can be delinked with several hydride, alkyl, aryl and vinyl nucleo...

PolyBorylated Alkenes as Energy-Transfer Reactive Groups: Access to Multi-Borylated Cyclobutanes Combined with Hydrogen Atom Transfer Event
Angew Chem Int Ed Engl. 2024 Apr 11:e202405898. doi: 10.1002/anie.202405898. Online ahead of print.ABSTRACTWhile polyborylated alkenes are being recognized for their elevated status as highly valuable reagents in modern organic synthesis, allowing efficient access to a diverse array of transformations, including the formation of C-C and C-heteroatom bonds, their potential as energy-transfer reactive groups has remained unexplored. Yet, this potential holds the key to generating elusive polyborylated biradical species, which can be captured by olefins, thereby leading to the construction of new highly-borylated scaffolds. H...

Commercializable Naphthalene Diimide Anolytes for Neutral Aqueous Organic Redox Flow Batteries
Angew Chem Int Ed Engl. 2024 Apr 11:e202405427. doi: 10.1002/anie.202405427. Online ahead of print.ABSTRACTNeutral aqueous organic redox flow batteries (AORFBs) hold the potential to facilitate the transition of renewable energy sources from auxiliary to primary energy, the commercial production of anolyte materials still suffers from insufficient performance of high-concentration and the high cost of the preparation problem. To overcome these challenges, this study provides a hydrothermal synthesis methodology and introduces the charged functional groups into hydrophobic naphthalene diimide cores, and prepares a series of...

In situ Formation of Platinum-Carbon Catalysts in Propane Dehydrogenation
Angew Chem Int Ed Engl. 2024 Apr 11:e202319887. doi: 10.1002/anie.202319887. Online ahead of print.ABSTRACTThe catalytic production of propylene via propane dehydrogenation (PDH) is a key reaction in the chemical industry. By combining operando transmission electron microscopy with density functional theory analysis, we show that the intercalation and ordering of carbon on Pt interstitials to form Pt-C solid solutions is relevant for increasing propylene production. More specifically, we found that at the point of enhanced propylene formation, the structure of platinum nanoparticles is transformed into a transient caesium ...

Synergistic Al-Al Dual-Atomic Site for Efficient Artificial Nitrogen Fixation
Angew Chem Int Ed Engl. 2024 Apr 11:e202405493. doi: 10.1002/anie.202405493. Online ahead of print.ABSTRACTSynthesis of ammonia by electrochemical nitrogen reduction reaction (NRR) is a promising alternative to the Haber-Bosch process. However, it is commonly obstructed by the high activation energy. Here, we report the design and synthesis of an Al-Al bonded dual atomic catalyst stabilized within an amorphous nitrogen-doped porous carbon matrix (Al2NC) with high NRR performance. The dual atomic Al2-sites act synergistically to catalyze the complex multiple steps of NRR through adsorption and activation, enhancing the prot...

Unraveling the Dynamic Molecular Motions of a Twin-Cavity Cage with Slow Configurational but Rapid Conformational Interconversions
Angew Chem Int Ed Engl. 2024 Apr 11:e202405858. doi: 10.1002/anie.202405858. Online ahead of print.ABSTRACTFeaturing diverse structural motions/changes, dynamic molecular systems hold promise for executing complex tasks. However, their structural complexity presents formidable challenge in elucidating their kinetics, especially when multiple structural motions are intercorrelated. We herein introduce a twin-cavity cage that features interconvertible C3- and C1-configurations, each configuration exhibiting interchangeable P- and M-conformations. This molecule is therefore composed of four interconnected chiral species (P)-C...

Large Libraries of Structurally Diverse Macrocycles Suitable for Membrane Permeation
Angew Chem Int Ed Engl. 2024 Apr 11:e202400350. doi: 10.1002/anie.202400350. Online ahead of print.ABSTRACTMacrocycles offer an attractive format for drug development due to their good binding properties and potential to cross cell membranes. To efficiently identify macrocyclic ligands for new targets, methods for the synthesis and screening of large combinatorial libraries of small cyclic peptides were developed, many of them using thiol groups for efficient peptide macrocyclization. However, a weakness of these libraries is that invariant thiol-containing building blocks such as cysteine are used, resulting in a region t...
