Proton Capture and Relay Codesign Enables a pH‐Neutral All‐Organic Aqueous Proton Battery

Jiyao Zhou, Jiapeng Zhao, Xinyue Deng, Xiaojing Sun et autres

ABSTRACT Aqueous all‐organic proton batteries promise safe, sustainable, and high‐rate energy storage, but operation under near‐neutral conditions is hindered by low proton activity and competition from nonproton charge carriers. Here, we report a proton capture and relay codesign strategy that enables proton‐dominated …

Electroreductive N-Debenzylation of Amines and Amide Derivatives in an Undivided Cell

Tianyi Zhang, Yi Wang, Hao Guo, Xin Li et autres

Direct electroreductive N-debenzylation of structurally diverse N-benzyl compounds was achieved in an undivided cell using a magnesium anode and carbon-felt cathode. Amines, N-heterocycles, amides, carbamates, ureas, lactams, and cyclic ureas were converted to the corresponding N-H products at room temperature without palladium …

Skeletal-Isomeric Scaffold Design Enables a Dipyrazole[3,4- b ;4′,3′- e ]pyrazine Platform for High-Density Energetic Materials

Wenjin Zhang, Yue Wang, Hui Wang, Yiling Yang et autres

Here we report a skeletal-isomeric scaffold design strategy for a fused N-heterocyclic energetic platform based on the dipyrazole[3,4- b;4′,3′- e ]pyrazine scaffold. This framework preserves planarity, symmetry, and π-conjugation while enabling distinct functionalization. On this basis, DNDP and TNDP were synthesized and …

Construction of high energy density azasydnone-pyrazole compounds

Wenjin Zhang, Yi Xue, He Huang, Chenghui Sun

The search for advanced energetic materials has shifted beyond traditional groups like nitro to explore non-conventional explosophores. Among these, the azasydnone ring stands out, combining a zero-oxygen balance with high-energy bonds (N-N, N-O, N=N) for stable energy storage. Here, we report the …

Carbonyl Modifying Bridge Strategy: Constructing High-Energy and Low-Sensitivity Energetic Materials

Yiling Yang, Wenjin Zhang, He Huang, Chenghui Sun

The bridged-ring strategy was a common approach to enhance the stability and number of modifiable sites for energetic compounds. However, changes in the bridging method can also lead to uncertainty in the energetic performance of the compound, and bridge replacement requires resynthesizing …

Photocatalytic Decarboxylative Alkylation of the C2-Position of 3-Haloindoles with Aliphatic Carboxylic Acids

Guanzheng Feng, Yisan Shen, Xiao-Jing Sun, Wenjin Zhang et autres

Indole is one of the most prevalent structural frameworks. Notably, C2-substituted indoles bearing an unsubstituted C3-position are recognized as privileged structural motifs in pharmaceutical synthesis. Here, we report a transition-metal-free photocatalytic decarboxylative coupling strategy employing 4CzIPN as the photocatalyst, enabling efficient and …
