Ketal Protection of Glycerol for Selective Electrosynthesis of Glyceric Acid in Highly Alkaline Media

Angewandte Chemie, EarlyView.
Using a ketal‐protected glycerol derivative (solketal) as the oxidation substrate enables site‐selective electrooxidation that suppresses C–C cleavage on non‐noble catalysts. Highly alkaline conditions promote reactive solketal alkoxide formation, weaken the Cα─H bond to facilitate dehydrogenation, and buffer local acidification, enabling a record‐high

Biophysical Characterization and Proteomic Analysis of Small Extracellular Vesicles Derived From Different Neural Cell Lines

Advanced NanoBiomed Research, EarlyView.
This study systematically compares small extracellular vesicles (sEVs) derived from four neural cell lines, revealing how cellular origin shapes vesicle biophysical properties and proteomic cargo. Distinct, lineage‐specific signatures linked to neuronal, astrocytic, and microglial functions are identified, highlighting the importance of cell source ...

Attractive Ni…O Interactions Enable Non‐Alternating Ethylene‐Carbon Monoxide Copolymerization

Angewandte Chemie, EarlyView.
Attractive Ni···O interactions are established in phosphine‐imidated and phosphine‐phenolate nickel catalysts, enabling non‐alternating ethylene‐carbon monoxide copolymerization, resulting in superior CO tolerance, productivity and stability compared to the state‐of‐the‐art benchmark.

Copper(II/III) Redox Couple Enables C─H Methylation via a Radical Mechanism Analogous to SAM Enzymes

Angewandte Chemie, EarlyView.
Biological C–H methylation proceeds through radical pathways mediated by one‐electron redox cofactors, yet no synthetic model has reproduced this reactivity. Here, we report the first isolable Cu(II/III)–methyl complexes that mediate C–H methylation through hydrogen atom transfer and methyl radical rebound.
