(Poly)Borylated Species as Modern Reactive Groups toward Unusual Synthetic Applications

Angewandte Chemie, EarlyView.
In this review, we spotlight recent breakthroughs in α‐polyboron‐substituted carbon‐centered intermediates (carbanion, carbocation, radical, and carbene) and polyborylated alkenes. By bridging fundamental reactivity with the application potential of these extraordinary species, we hope this review will serve as a roadmap for harnessing these unique ...

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.

Low‐Carbon Poly(3‐vinyl‐N‐methylphenothiazine) Electrode Formulation Using PEDOT:PSS (poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate)) for Lithium‐Based Energy Storage

Advanced Energy and Sustainability Research, EarlyView.
Organic electrode materials typically suffer from low electronic conductivity, requiring large amounts of carbon additives. Herein, a conducting polymer, PEDOT:PSS, is introduced as a partial replacement for carbon black, reducing the carbon content to 15 wt%.

Photothermal Conversion Promotes Challenging SNAr for Facile C─N Bond Formation

Angewandte Chemie, EarlyView.
Photothermal conversion enables facile aromatic C─N bond formation via red light irradiation. A variety of inter‐ and intramolecular SNAr transformations are achieved under mild, schematically simple conditions. Additionally, a thermally promoted halogen exchange mechanism provides access to aryl bromides, chlorides, and fluorides – making this ...

Development and systematic evaluation of triamine‐based functional deep eutectic solvents for efficient CO2 capture

AIChE Journal, EarlyView.
Abstract The development of advanced absorbents for effectively capturing carbon dioxide is crucial in mitigating greenhouse gas emissions. This study introduced a series of deep eutectic solvents (DESs) for CO2 capture and identified the most promising DESs with the stepwise screening method based on their absorption capacity, absorption rate, thermal
