Visible-light Promoted Atom Transfer Radical Addition−Elimination (ATRE) Reaction for the Synthesis of Fluoroalkylated Alkenes Using DMA as Electron-donor
Autor: Wen-Wen Xu, Le Wang, Ting Mao, Jiwei Gu, Xiao-Fei Li, Chun-Yang He
Publikováno v: Molecules, Vol 25, Iss 3, p 508 (2020)
Here, we describe a mild, catalyst-free and operationally-simple strategy for the direct fluoroalkylation of olefins driven by the photochemical activity of an electron donor−acceptor (EDA) complex between DMA and fluoroalkyl iodides. The significa

Synthesis of Secondary Trifluoromethylated Alkyl Bromides Using 2-Bromo-3,3,3-trifluoropropene as a Radical Acceptor
Autor: Peng Guo, Maoling Tao, Wen-Wen Xu, An-Jun Wang, Weipiao Li, Qiuli Yao, Jie Tong, Chun-Yang He
Publikováno v: Organic Letters. 24:2143-2148
Herein, the first example using commercially available 2-bromo-3,3,3-trifluoropropene (BTP) as a radical acceptor has been reported. Taking advantage of this strategy, a wide range of secondary trifluoromethylated alkyl bromides were synthesized in g

Autor: Nan-Wei Wan, Wenyong Han, Chun-Yang He, Yongzheng Chen, Yong-Chao Shao, Jia-Li Huang, Baodong Cui, An-Ni Wang, Wen-Wen Zhao
Publikováno v: Organic Letters. 23:9256-9261
We present herein a visible-light-induced [3 + 2] cycloaddition of a hypervalent iodine(III) reagent with α-ketoacids for the construction of 5-CF3-1,3,4-oxadiazoles that are of importance in medicinal chemistry. The reaction proceeds smoothly witho

Visible light induced deaminative alkylation of difluoroenoxysilanes: a transition metal free strategy
Autor: Yang Huang, Liang Zhao, Qi-Ping Huang, Yanbo Yu, Jia Jia, Jiwei Gu, Jie Tong, An-Jun Wang, Chun-Yang He
Publikováno v: Organic Chemistry Frontiers. 8:4438-4444
Hantzsch ester, a widely used base or electron-donor compound, was found to act as a catalyst in the deaminative difluoroalkylation reaction utilizing Katritzky salts and difluoroenoxysilane as substrates; this represents a rare catalytic example of

Iron-catalyzed C–F bond silylation and borylation of fluoroarenes
Autor: Zhang Feng, Zhengli Liu, Minghui Sun, Weipiao Li, Liang Zhao, Maoling Tao, Chun-Yang He
Publikováno v: Organic Chemistry Frontiers. 8:5322-5327
Iron-catalyzed functionalization of inert bonds has scarcely been documented. Herein, we report an iron-catalyzed method for the silylation and borylation of (hetero)aromatic fluorides. This protocol features a wide range of substrates, high efficien

Iron-Catalyzed Silylation of (Hetero)aryl Chlorides with Et3SiBpin
Autor: Xiaoqin Zeng, Xiao-Fei Li, Zhang Feng, Jia Jia, Liang Zhao, Zhengli Liu, Chun-Yang He
Publikováno v: Organic Letters. 22:2816-2821
To date, the iron-catalyzed construction of C–heteroatom bonds has been less developed due to the difficulty of transmetalation with heteroatom anions and the sluggish reductive elimination. Herein...
