Halide Bond Assisted Double Desymmetrization of Meso‐Dicarboxylic Acids with Symmetrical Olefins via Asymmetric Halogenation

Angewandte Chemie, EarlyView.
This work demonstrates a double desymmetrization of meso‐dicarboxylic acids with symmetrical olefins, constructing complex chiral lactones with six stereocenters in one step. Unexpectedly, the halide bond was found to be crucial in achieving high stereoselectivity.

Multicatalytic Access to Renewable Poly(Silyl Ether)s with Tunable Properties

Angewandte Chemie, EarlyView.
This work presents a one‐pot, multicatalytic approach that combines magnesium‐catalyzed esterification and borane‐mediated hydrosilylation for the synthesis of partially bio‐based poly(silyl ethers). This method allows for the tuning of thermal and mechanical properties, including exceptional extensibility (>3800%), and enables efficient chemical ...

One‐Pot Incorporation of Quantum Defects into Single‐Walled Carbon Nanotubes with Arylazo Sulfonates

Angewandte Chemie, EarlyView.
We present a photochemical strategy to create complex aromatic quantum defects in carbon nanotubes using arylazo sulfonates. It provides access to brighter carbon nanotubes without purification and simpler biofunctionalization. Abstract Single‐walled carbon nanotubes (SWCNTs) consist of a carbon monolayer and fluoresce in the near‐infrared (NIR, 800 ...

Reimagining o‐Carborane‐Based Fluorophores: Charge‐Transfer from Boron Substituents Triggers Aggregation‐ and Crystallization‐Induced Emission

Angewandte Chemie, EarlyView.
This work reports, for the first time, aggregation‐ or crystallization‐induced emission in boron‐substituted carboranes, which was driven by photoinduced charge‐transfer from fluorophore attached via boron vertices. The emission properties can be tuned by varying the substituents, expanding design strategies for luminescent materials.

Selective Hydrodemethylation of Methylalkylbenzenes on Potassium Hydride

Angewandte Chemie, EarlyView.
Selective catalytic hydrodealkylation of methylalkylbenzenes on carbon‐supported potassium hydride is reported. The reaction exhibits a reactivity trend of 1° ∼ 2° ∼ 3° < CH3, which is opposite to traditional dealkylation and hydrodealkylation. DFT calculations on the (001) facet of KH with ortho‐ethyltoluene suggest that selectivity is controlled by ...
