cis-Bromination of Alkynes without cationic intermediates.
, 2005 Surprising insight into a classical mechanism is provided by theoretical and experimental investigations on the bromination of alkynes. In nonpolar solvents the bromination of acetylene via a covalent tribromide adduct is strongly favored over the ...

Advanced Science, EarlyView.The ABCABC stacking sequence in 2D ZnIn2S4 nanosheets creates intrinsic non‐centrosymmetry, enabling robust piezocatalysis under weak mechanical agitation. The nanosheets achieve a H2O2 yield of 276.7 µmol g−1 h−1 and uranium extraction capacity of 763.2 mg g−1 via a dual mechanism of direct piezoreduction and in situ H2O2 complexation.

Polarization Engineering in Vinylene‐Linked COFs Toward Efficient Neuromorphic Computing
Advanced Science, EarlyView.A vinyl‐linked covalent organic framework (COF‐DIBPY) was synthesized on a conductive substrate for memristor applications. Redox reactions and bromide migration enable low‐voltage (0.5V) conductance switching with high analog on/off ratio (15.7). The device was further integrated into a speech emotion recognition system for acoustic simulation and ...

Advanced Science, EarlyView.This study reports D34 as the first PROTAC degrader that targets the 3C protease of picornaviruses. D34 effectively degrades EV71 3C protease via the ubiquitin‐proteasome pathway. More importantly, D34 exhibits a high resistance barrier and shows broad‐spectrum antiviral activity against multiple picornaviruses, highlighting its potential as a novel ...

Modular and Stereoselective Synthesis of Cyclobutane β‐Amino Alcohols
Angewandte Chemie, EarlyView.Late‐stage functionalization and photoisomerization of 1,2‐azaborine leads to a general strategy for the synthesis of diversely substituted cyclobutane β‐amino alcohols. The relative stereochemistry of the resulting products is unambiguously defined by the stereospecific and stereoselective nature of the photoisomerization‐hydrogenation‐oxidation ...

Polybromides Attraction‐Repulsion Regulation Promotes High‐Performance Zinc–Bromine Static Battery
Advanced Science, EarlyView.Br3− attraction‐repulsion regulation enhances the reversibility and reaction kinetics of Zn–Br static batteries. Coin cell shows a high average discharge voltage of 1.73 V and a fast charge/discharge rate up to 32 mA cm−2. Pouch cell with a high areal capacity of 8.3 mAh cm−2 achieves a real capacity of 365 mAh after 100 cycles.

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.

Oxidative Bromination of Methane on Supported Metal Oxide Catalysts
, 2008 Methane oxidative bromination reaction was carried out on five supported metal oxide catalysts (V, Ce, Mo, Ba, WOx/SiO2). All the catalysts showed roughly the same activity but the selectivity fell into two parts.
