Photo‐Triggered, Fast, and Fluorogenic Thiophene‐Based Cycloalkynes for the Bioorthogonal Fluorescent Labeling of 1,3‐Dipole‐Tagged Molecules in No‐Wash Conditions

Angewandte Chemie, EarlyView.
Thiophene is king! The fusion of thiophene rings to cycloalkynes super‐charged their copper‐free click chemistry applications, by (1) enhancing the alkyne reactivity (fastest cyclooctyne to date) and (2) rendering the alkyne fluorogenic (with fluorescence enhancement up to 150‐fold upon reaction), making these bioorthogonal reagents ideal for tracking ...

Cell Labeling with 15-YNE Is Useful for Tracking Protein Palmitoylation and Metabolic Lipid Flux in the Same Sample

Molecules
Protein S-palmitoylation is the process by which a palmitoyl fatty acid is attached to a cysteine residue of a protein via a thioester bond. A range of methodologies are available for the detection of protein S-palmitoylation.

Fabrication of Composite Cathode for All‐Solid‐State Sodium Batteries

Advanced Energy Materials, EarlyView.
The design of composite cathodes for all‐solid‐state sodium batteries must address three critical challenges—interfacial side reactions, interfacial delamination, and highly tortuous transport pathways. This work outlines structural and interfacial strategies to optimize ion transport and mechanical stability, enabling durable, and high‐performance ...

Metabolic Labeling and Visualization of Isoprenoids Using Alkyne‐Modified DMAPP Analogs in Bacillus subtilis

Angewandte Chemie, EarlyView.
Fluorescence‐based visualization and targeted mass–spectrometric enrichment of membrane‐embedded isoprenoids in Bacillus subtilis via cell‐permeant, alkynylated DMAPP analogs. ABSTRACT Isoprenoids are a chemically and functionally diverse class of metabolites that underlie essential bacterial physiology including respiration and cell envelope ...

Bioorthogonal Tools for Ethanolamine Lipids and Protein Conjugates

Angewandte Chemie, EarlyView.
An alkyne‐tagged ethanolamine analog (AlkEA) enables bioorthogonal, metabolic labeling of endogenous phosphatidylethanolamine (PE) and its protein modifications. AlkEA is incorporated into PE via the Kennedy pathway, allowing CuAAC‐based visualization of PE and affinity capture of PE‐conjugated LC3, ubiquitin, and GPI‐anchored proteins.

Alkyne dichotomy and hydrogen migration in binuclear cyclopentadienylmetal alkyne complexes

RSC Advances
Low-energy (Me2N)2C2M2(C5H5)2 (M = Ni, Co, Fe) structures have central Mn2C2 tetrahedrane units or separate bridging Me2NC carbyne units. However, low-energy (Me2NC2Me)M2(C5H5)2 and Me2C2M2(C5H5)2 structures exhibit hydrogen migration from the methyl substituent.

A Cholesterol Analogue for Cell‐Surface Enzyme Display

Angewandte Chemie, EarlyView.
We report a non‐genetic strategy for bacterial cell surface enzyme immobilisation using cholesterol‐based artificial lipids containing Ni2+‐NTA binding groups that can integrate into biological membranes. The engineered cells can capture His‐tagged enzymes directly from cell lysates while preserving intracellular and surface activity, allowing for ...

Isolable C‐Phosphonio‐Boratavinyl Anion

Angewandte Chemie, EarlyView.
A persistent C‐phosphonio boratavinyl anion was successfully synthesized. This boron‐containing vinyl lithium, featuring a vinyl carbon with an excessively high negative charge, exhibits remarkable nucleophilic and basic character, which was demonstrated by the result of a rapid reaction with H2 at RT.

Divergent Synthesis of Möbius and Hückel N‐Heterocycloarenes From a Common Macrocyclic Backbone

Angewandte Chemie, EarlyView.
In the divergent synthesis of Möbius and Hückel N‐heterocycloarenes from a common macrocyclic precursor, the annulation reaction dictates topology: Scholl reaction gives Möbius topology, while InCl3‐mediated alkyne annulation gives Hückel topology. The Möbius N‐heterocycloarene is unevenly contorted as revealed by crystal structure, and the Hückel N ...

Kinetic Analysis of Transmetalation at Prototypical Nickel(II) Catalyst Species: Rates, Mechanisms, and Implications for Catalysis

Angewandte Chemie, EarlyView.
A 31P{1H} NMR method enabling direct measurement of transmetalation at Ni(II) is disclosed, providing an extensive kinetic dataset. Rates span five orders of magnitude and exhibit strong ligand dependence, with monodentate ligands promoting transmetalation.
