Synergistic silver-mediated and palladium-catalyzed nondirected olefination of aryl C–H bond: quick access to multi-substituted aryl olefins Sci. China Chem. (IF 9.6) Pub Date : 2023-12-19
Abstract Transition metal-catalyzed olefination of aryl C–H bond is a powerful tool for the synthesis of alkenes. While the Pd-catalyzed oxidative C–H olefination of arenes, also known as Fujiwara-Moritani reaction, has been established as one of the most efficient methods, the substrates are largely limited to terminal olefins with electron-withdrawing group(s). Herein, we report a synergistic silver-mediated

Bimolecular reduction of carbon dioxide: double synthons for alkynes trifunctionalization Sci. China Chem. (IF 9.6) Pub Date : 2023-12-14 Wenfang Xiong, Xiaobin Tan, Hongjian Liu, Baiyao Zhu, Jinwu Zhao, Jianxiao Li, Chaorong Qi, Huanfeng Jiang
Carbon dioxide reduction, as a sustainable and versatile strategy for the access of chemical fuels, has attracted increasing attention and enormous efforts have been devoted to it in recent years. However, employing carbon dioxide as double synthons via bimolecular reduction remains challenging. Here, by leveraging the bimolecular reduction of carbon dioxide to carbonyl and methyl respectively, we

CAr–Br bond cleavage via cooperative EnT/NHC catalysis: mild access to indolines Sci. China Chem. (IF 9.6) Pub Date : 2023-12-08 Yi-Xiong Dong, Cao-Bo Li, Ming-Lei Jin, Zhong-Hua Gao, Song Ye
The cooperative visible-light mediated and NHC-catalyzed dearomative arylation-acylation of N-(2-bromobenzoyl)indoles with aldehydes was developed, affording the corresponding highly functionalized polycyclic indolines in moderate to good yields with exclusive diastereoselectivities. Mechanism investigations support the activation of CAr–Br bond via visible-light mediated energy transfer (EnT) and

Recent advances in Fe–N–C- and Co–N–C-based materials as bifunctional electrocatalysts for oxygen reduction and oxygen evolution Sci. China Chem. (IF 9.6) Pub Date : 2023-12-05 Hui-Min Xu, Hong-Rui Zhu, Chen-Jin Huang, Zhi-Jie Zhang, Ting-Yu Shuai, Qi-Ni Zhan, Gao-Ren Li
Fe-nitrogen-carbon (Fe–N–C)- and Co-nitrogen-carbon (Co–N–C)-based electrocatalysts have been widely concerned because of their high OER/ORR activity, low metal cost, and simple preparation. The exploration of Fe–N–C and Co–N–C single atom-based catalysts with high activity and stability to overcome the slow kinetics of oxygen reduction and oxygen evolution reactions is also the key to the development

Bioinspired zinc-mediated umpolung thiolation of alkyl electrophiles: reaction development, scope and mechanism Sci. China Chem. (IF 9.6) Pub Date : 2023-12-04 Yuenian Xu, Yan Zhang, Yong Liu, Wen-Wu Sun, Jie Huang, Hui He, Yingjie Wu, Wen Liu, Shao-Fei Ni, Xu-Qiong Xiao, Xinxin Shao
Zinc-promoted umpolung thiolation of alkyl electrophiles with masked sulfur transfer reagents in the absence of nickel or copper catalysis is described. This protocol proceeds via a SET process of Zn to electrophilic sulfur reagent followed by insertion of Zn into disulfide and nucleophilic thiolation, providing straightforward access to a wide range of alkyl sulfides with broad substrate scope. A

SO2-Insertion induced enantioselective oxysulfonylation to access β-chiral sulfones with quaternary carbon stereocenters Sci. China Chem. (IF 9.6) Pub Date : 2023-12-05 Jun Zhang, Xuefeng Wang, Peiqi Wang, Jiayuan Fang, Shaoyu Li, Jie Wu
β-Chiral sulfones are structural motifs widely found in natural products and bioactive molecules, while also serving as important intermediates for the synthesis of valuable chiral scaffolds. In contrast to the rapid growth of sulfur dioxide insertion chemistry over the last decade, enantioselective catalytic variants for accessing β-chiral sulfones, especially those bearing a quaternary carbon stereocenter

Ni-catalyzed highly regio- and stereo-selective diborylative cyclization of 1,6-enynes with diboron reagent Sci. China Chem. (IF 9.6) Pub Date : 2023-12-05 Qitao Guan, Zhen Shen, Yiqiang Tian, Genping Huang, Chun Zhang
The Ni-catalyzed highly selective diborylative cyclization of 1,6-enynes with diboron reagent has been developed. When pinB-Bdan was used, multiple types of boron-containing functional groups could be installed into organic molecule with great chemoselectivity and regioselectivity though this reaction. Meanwhile, if B2pai2 was employed, the asymmetric diborylative cyclization could be well induced

Quantitative understanding of phase segregation behaviors by precisely building discrete oligo-ester-b-oligo-olefin block copolymers Sci. China Chem. (IF 9.6) Pub Date : 2023-11-29 Yuxin Liu, Rui Tan, Haibing Wu, Xue-Hui Dong, Zhengbiao Zhang
Block copolymers (BCPs) with high Flory-Huggins parameter (χ) and balanced surface energy have aroused tremendous interest for ultra-small nanopatterns processing. However, high χ and balanced surface energy are generally contradicted. The fine tune of chain structure might be a useful way to achieve high χ and balanced surface energy. To realize this, the block copolymer with exactly uniform chain

Solution processability is a unique property of organic semiconductors. The compact and regular n-n stacking between molecules is paramount in the performance of organic optoelectronic devices. However, it is still a challenge to improve their stacking quality without sacrificing the solution-processability from the aspect of materials design. Here, delicately engineered additives are presented to
