Room‐Temperature Gas‐Phase CO2‐to‐C3 Coupling by a 4f‐Aromatic Cluster

open access: yesAngewandte Chemie, EarlyView.
We engineered a 4f metalla aromatic cluster, PrB2C2−, that enables efficient sequential C−C coupling with CO2 at room temperature, yielding a linear C3 backbone. This system provides a complete theoretical catalytic cycle and establishes a new design principle for lanthanide mediated CO2 activation.

Intermolecular Electrophilic Germylation Using GeCl4 and Al2Cl6

open access: yesAngewandte Chemie, EarlyView.
While electrophilic aromatic substitution is well‐established for carbon and silicon‐based electrophiles, it is extremely underdeveloped for germanium. Herein we report the first effective intermolecular Germa–Friedel–Crafts reaction. The process can be modified to enable selective synthesis of the mono‐ or the di‐aryl germane derivatives, ArGeCl3 and ...

Site‐Selective B─H Activation via HAT Toward Xanthyl‐closo‐Carboranes as Bench‐Stable Precursors of Organosulfur Boron Clusters

open access: yesAngewandte Chemie, EarlyView.
A light mediated direct regioselective B─H functionalization, via hydrogen atom transfer (HAT), is described. Unexplored xanthyl‐closo‐carboranes as novel bench‐stable and versatile platforms to access sulfur‐containing boron clusters are reported for the first time.

Sequence‐Encoded Frustration Directs the Formation of Abridged G‐Quadruplex Architectures

open access: yesAngewandte Chemie, EarlyView.
Programmable frustration reshapes the free‐energy surface (FES) of guanine‐quadruplex (G4) folding, stabilizing an abridged G4 and a G‐triplex intermediate. ABSTRACT Frustration—competing interactions that cannot be simultaneously optimized—shapes energy landscapes in proteins and soft matter, but has rarely been exploited as a programmable design ...

Dual‐Sabatier Optima: How Reaction Mechanism Determines Activity Volcano Map of Dual‐Atom Catalysts for Oxygen Reduction Reaction

open access: yesAngewandte Chemie, EarlyView.
Dual‐atom catalysts (DACs) for oxygen reduction reaction (ORR), where the dissociative mechanism dominates, show a dual‐Sabatier optima volcano map, diverging from the classical single‐peak volcano of the associative mechanism. Potential‐dependent microkinetic modeling and interpretable machine learning rationalize experimental data and provide design ...

A Circular and Tacticity‐Independent Crystalline Mono‐Substituted Nylon‐6 Platform: Unexpected Large Positional Effects on Crystallizability and Performance

open access: yesAngewandte Chemie, EarlyView.
Methyl substitution positions on the nylon‐6 backbone markedly affect crystallizability, thermomechanical properties, and recyclability of the resulting atactic nylon‐6 variants. While γ‐methyl substitution gives an amorphous nylon, all other four methyl‐substitution positions (α, β, δ, and ε) afford, unexpectedly, crystalline nylons, showing tacticity‐
