Proximal and Remote Hydrocarboxylation of Alkenes with Carbon Dioxide Enabled by Nickel‐Catalyzed Hydrogen Atom Transfer

Angewandte Chemie, EarlyView.
The use of carbon dioxide and alkenes as feedstocks for the production of carboxylic acids holds great significance in sustainable chemistry. Herein, we introduce a simple and unifying nickel‐catalyzed radical hydrocarboxylation for both functionalized and unactivated alkenes at proximal and remote sites.

Effect of Alternating Polarity in Electrochemical Olefin Hydrocarboxylation

Angewandte Chemie, EarlyView.
Alternating polarity (AP) is a powerful tool for controlling selectivity in olefin hydrofunctionalization, but this use is underdeveloped. Using electrochemical olefin hydrocarboxylation as a model, we highlight how AP controls product selectivity, yield, and material decomposition.

Facile Access to Piezoelectric Polyamides by Polyamidation of Carboxylic Acids and Ynamides for Potent Tumor Immunotherapy

Angewandte Chemie, EarlyView.
We establish a simple polyamidation of carboxylic acids and ynamides to synthesize versatile piezoelectric polyamides, with the merits of 100% atom economy, no waste generation, and additive‐free as well as catalyst‐free system. Tetraphenylethene containing polyamides can generate reactive oxygen species and elicit robust immunogenic cell death ...

Donor‐π‐Acceptor Photoinitiators for High‐Efficiency Visible LED and Sunlight Polymerization and High‐Precision 3D Printing

Angewandte Chemie, EarlyView.
The proposed D‐π‐A structured dyes enable efficient electron transfer with additives, thanks to their tailored architecture, making them ideal for high‐performance photoinitiating systems. They allow the fabrication of high‐precision 3D printed objects and exhibit outstanding performance under sunlight.
