1Transition Metal-Catalyzed Allylic C(sp3)-H Functionalization via η3-Allylmetal Intermediate显示文摘1.Introduction The past few decades have witnessed extensive studies on transition metal-catalyzed C-H bond activations and subsequent carbon-carbon and/or carbon-heteroatom bond formations because these methods provide more atom-and step-economical pathways than those traditional transformations starting from prefunctionalized substrates.Ronghua Wang Yuxin Luan Mengchun Ye 2019Chinese Journal of Chemistry2019,37,7:7
2Bimetallic anchoring catalysis for C–H and C–C activation显示文摘Following the age of directing group,anchoring catalysis starts coming to the center of the stage.Different from the directinggroup strategy that needs a preinstalled directing group in substrates,anchoring catalysis relies on a reversible interaction between a substrate and a catalyst,which then directs metal to activate inert chemical bonds.Such reversible directing effect not only generates good site-and stereo-selectivity as traditional directing groups do but also eliminates the requirement of stoichiometric amounts of directing groups.Among variously reported anchoring catalysis,coordinative bimetallic anchoring catalysis in general displays superior reactivity than others because coordinative bonding not only affords strong interaction of catalysts with substrates but also displays good compatibility with substrates and reaction conditions.In recent years,big progress has been achieved for coordinative bimetallic anchoring catalysis.This review gave a detailed summary of this field,including catalyst development,catalyst types,reaction types and reaction mechanisms.Jiang-Fei Li Yu-Xin Luan Mengchun Ye 2021Science China Chemistry2021,64,11:2
3Well-Designed Chiral Ligands for Enantioselective Ir-Catalyzed C(sp^2)-H Borylatior显示文摘Due to the lack of proper chralgands,enantioselectve C(sp^2)-H borylation has been a challenging goalfor a long time.Recently,threedifferent types ofwel-designed chiral ligands were developed,not only addressing this challenge but also providing a good inspiration for the future development of otherasymmetric reactions.Yin-Xia Wang Ping-Feng Zhang Mengchun Ye 2020Chinese Journal of Chemistry2020,38,12:1
4Nickel-Catalyzed Reductive Coupling of Aldehydes with Alkynes Mediated by Alcohol显示文摘A nickel-catalyzed reductive coupling of aldehydes with aikynes using 1-phenylethanol as reducing agent has been developed.The key achievement of this work is that we demonstrate environmentally benign 1-phenylethanol can serve as a viable alternative reducing agent to Et3B,ZnEt2 and R3SiH for the nickel-catalyzed reductive coupling reaction of aldehyde and alkynes.Yan-Long Zheng Mengchun Ye 2020Chinese Journal of Chemistry2020,38,5:1
5Recent advances in Ni-Al bimetallic catalysis for unreactive bond transformation显示文摘Ni-Al bimetallic catalysis proves to be an efficient catalytic strategy for unreactive bond transformations. Recently, chiral bifunctional ligands, especially amphoteric secondary phosphine oxide(SPO) ligand, are used for a more powerful synergistic effect in the bimetal-catalyzed reactions, providing not only milder reaction conditions and higher reactivity but also excellent reaction selectivity. Herein, we give a brief review on the development of Ni-Al bimetallic catalytic system and highlight recent advances in enantioselective Ni-Al bimetallic catalysis for unreactive bond transformation.Yin-Xia Wang Mengchun Ye 2018Science China Chemistry2018,61,8:0
6Nickel-and Brønsted Acid-Catalyzed Redox-Neutral Coupling of 1,3-Dienes and Aldehydes for Synthesis of Dienols显示文摘Dienols are important structural motifs in organic molecules,but most of the traditional synthetic methods required multistep prefunctionalization of substrates,leading to stoichiometric waste and low atom economy.Herein,we report a redox-neutral coupling of simple 1,3-dienes and aldehydes via nickel and Brønsted acid dual catalysis,providing a highly atom-economical and by-product-free route to various dienols with up to 94%yield and up to 50∶1 EE/EZ ratio.The use of 2-isopropoxyphenol as a Brønsted acid co-catalyst was critical to the reactivity and selectivity.Xing-Wang Han Tao Zhang Wei-Wei Yao Hao Chen Mengchun Ye 2021CCS Chemistry2021,3,3:0
