Copper‐Catalyzed Enantioselective Dehydro‐Diels–Alder Reaction: Atom‐Economical Synthesis of Axially Chiral Carbazoles Angew. Chem. Int. Ed. (IF 16.1) Pub Date : 2024-09-13 Hua-Hong Chen, Yang-Bo Chen, Jun-Zhe Gao, Long-Wu Ye, Bo Zhou
The dehydro‐Diels–Alder (DDA) reaction is a powerful method for the construction of aromatic compounds. However, the enantioselective DDA reaction has been rarely developed, probably due to the competitive thermal reaction. Herein, we report a copper‐catalyzed enantioselective DDA reaction through vinyl cation pathway. The reaction leads to the atom‐economical synthesis of axially chiral phenyl and

Photocatalyzed Aryl C‐H Fluorocarbonylation with CF2Br2 Angew. Chem. Int. Ed. (IF 16.1) Pub Date : 2024-09-13 Kehan Zhou, Yuheng Xiao, Zhibin Huang, Yingsheng Zhao
The use of abundant and inexpensive fluorine feedstocks to synthesize fluorinated compounds is a promising strategy that has not been extensively investigated. Dibromodifluoromethane (CF2Br2) is an inexpensive fluorine source that has rarely been used for C‐H fluoroalkylation. This study reveals an iridium‐catalyzed, tunable strategy for synthesizing acyl fluorides and difluorobromomethylated products

Highly Stable Propane Dehydrogenation on a Self‐supporting Single‐component Zn2SiO4 Catalyst Angew. Chem. Int. Ed. (IF 16.1) Pub Date : 2024-09-13 Zhaohui Liu, Min Mao, Tie Shu, Qingpeng Cheng, Dong Liu, Jianjian Wang, Yun Zhao, Lingmei Liu, Yu Han
Current industrial propane dehydrogenation (PDH) processes predominantly use either toxic Cr‐based or expensive Pt‐based catalysts, necessitating urgent exploration for alternatives. Herein, we present Zn2SiO4, an easily prepared, cost‐effective material, as a highly efficient and stable catalyst for PDH. Uniquely, Zn2SiO4 nanocrystals do not require dispersion on support materials, commonly needed

Wavy Graphene Nanoribbons Containing Periodic Eight‐Membered Rings for Light‐Emitting Electrochemical Cells Angew. Chem. Int. Ed. (IF 16.1) Pub Date : 2024-09-13 Xinliang Feng, Sebastian Obermann, Xin Zhou, L. Andrés Guerrero-León, Gianluca Serra, Steffen Böckmann, Yubin Fu, Evgenia Dmitrieva, Jin-Jiang Zhang, Fupin Liu, Alexey A. Popov, Andrea Lucotti, Michael Ryan Hansen, Matteo Tommasini, Yungui Li, Paul W. M. Blom, Ji Ma
Precision graphene nanoribbons (GNRs) offer distinctive physicochemical properties that are highly dependent on their geometric topologies, thereby holding great potential for applications in carbon‐based optoelectronics and spintronics. While the edge structure and width control has been a popular strategy for engineering the optoelectronic properties of GNRs, non‐hexagonal‐ring‐containing GNRs remain

Diatomic Catalysts for Aqueous Zinc‐Iodine Batteries: Mechanistic Insights and Design Strategies Angew. Chem. Int. Ed. (IF 16.1) Pub Date : 2024-09-13 Peng Hei, Ya Sai, Wenjie Li, Jianming Meng, Yulai Lin, Xiaoqi Sun, Jing Wang, Yu Song, Xiao-Xia Liu
There has been a growing interest in developing catalysts to enable the reversible iodine conversion reaction for high‐performance aqueous zinc‐iodine batteries (AZIBs). While diatomic catalysts (DACs) have demonstrated superior performance in various catalytic reactions due to their ability to facilitate synergistic charge interactions, their application in AZIBs remains unexplored. Herein, we present

A Dual Purpose Non‐Canonical Amino Acid for the Expanded Genetic Code: Combining Metal‐Binding and Click Chemistry Angew. Chem. Int. Ed. (IF 16.1) Pub Date : 2024-09-13 Graham J. Day, Andrey V. Zaytsev, Richard C. Brewster, Valery N. Kozhevnikov, Amanda G. Jarvis
A rationally designed dual purpose non‐canonical amino acid (Trz) has been synthesised and successfully incorporated into a protein scaffold via genetic code expansion. Trz contains a 5‐pyridyl‐1,2,4‐triazine system, which allows for inverse electron‐demand Diels–Alder (IEDDA) reactions to occur on the triazine ring and for metal ions to be chelated both before and after the click reaction. Trz was

Glycosylated AIE‐active Red Light‐triggered Photocage with Precisely Tumor Targeting Capability for Synergistic Type I Photodynamic Therapy and CPT Chemotherapy Angew. Chem. Int. Ed. (IF 16.1) Pub Date : 2024-09-13 Wei Zhou, Yi-chen Liu, Guang-jian Liu, Yuan Zhang, Gai-li Feng, Guo-wen Xing
Photocaging is an emerging protocol for precisely manipulating spatial and temporal behaviors over biological activity. However, the red/near‐infrared light‐triggered photolysis process of current photocage is largely singlet oxygen (1O2)‐dependent and lack of compatibility with other reactive oxygen species (ROS)‐activated techniques, which has proven to be the major bottleneck in achieving efficient

Template‐assisted Flexible‐to‐rigid Transition of Peptides in Head‐to‐tail Self‐polymerization Enables Sequence‐controllable and Post‐modifiable Peptide Nanofibers Angew. Chem. Int. Ed. (IF 16.1) Pub Date : 2024-09-13 Tianzi Chen, Yin Liu, Zhanshan Gao, Yue Gao, Haijin Chen, Haonan Ye, Qiuhao Luo, Kefeng Wang, Dongdong WU
Peptide‐based nanofibers are promising materials for many essential applications and can be generalized into two categories, self‐assembling peptide nanofibers (SAPNs) and poly(amino acid) nanofibers (PAANs). Non‐covalent SAPNs are sequence‐controllable, but poorly stable and not suitable for post‐modification. While covalent PAANs are post‐modifiable, however, their sequences are either monotonic

By highly efficient ligand‐exchange strategy, atomically precise Au8Pd1(PPh3)82+ (PPh3 = triphenylphosphine) cluster can be transformed into a Au8Pd1(DPPF)42+ (DPPF = 1,1'‐bis(diphenylphosphino)ferrocene) cluster that can maintain the atomic‐packing structure but overcome the lability of Au8Pd1(PPh3)82+. Catalytic evaluation for the CO2 hydrogenation coupled with o‐phenylenediamine demonstrates that
